OPINION
John Rogers, a former Kentucky State Senator, appeals his convictions for conspiracy to commit extortion and attempted extortion under color of official right in violation of 18 U.S.C. § 1951 (Counts One and Two), mail fraud in violation of 18 U.S.C. §§ 1341 and 1346 (Count Three), and making a materially false statement to a federal agent in violation of 18 U.S.C. § 1001 (Count Four). For the reasons that follow, we affirm Rogers’s convictions.
I. BACKGROUND
In 1983, Rogers, State Senator Frank Miller, and lobbyists Jay Spurrier and William Wester agreed to accept compensation from businessman/banker Wallace Wilkinson in exchange for their efforts to secure the passage of the Multi-Bank Holding Company Bill (“the Banking Bill”). The Banking Bill, which had been defeated by a narrow margin in 1982, would permit Kentucky banks to expand across county lines. The conspirators planned for Wilkinson to purchase a bank in Bowling Green, Kentucky after the Banking Bill passed. After a while, Wilkinson would sell the bank and share half of the profits with Rogers, Miller, Wester, and Spurrier. The Banking Bill passed in April 1984, and Wilkinson purchased a bank in Bowling Green a little over a year later in June 1985. Wilkinson was elected Governor of Kentucky in November, 1987, and while he held that office, the conspirators did not attempt to collect any money from him.
In January of 1992, when Spurrier was arrested for his participation in an unrelated criminal scheme, he told the FBI about the Banking Bill conspiracy. Spurrier agreed to cooperatе with the FBI by recording conversations with the other conspirators in which they discussed their deal and their plan for obtaining their share of the bank profits from Wilkinson. During one meeting that Spurrier recorded, Rogers, Miller, Wester, and Spurrier decided to take several photos of *470 themselves next to a life-sized cardboard photo of Wilkinson. See J.A. at 122. Rogers mailed the pictures to Wilkinson with a note to remind him of their deal, stating that the group “had a meeting and it was good [and] this picture just reminded me that we need to have a board of directors meeting some time soon [and that Rogers would] be in touch.” J.A. at 130. 1
Thereafter, Rogers, Miller, Wester, and Spurrier repeatedly attempted to contact Wilkinson. On March 3, 1992, Rogers, Wester, and Spurrier met to discuss their progress in contacting Wilkinson and to estimate the amount they would receive from the sale of the bank. On March 5, Wester, Spurrier, and Miller called Wilkinson to determine whether the photograph Rogers sent to Wilkinson had the desired effect. On March 10, Wester, Spurrier, Miller, and Rogers met again to discuss the passage of the Banking Bill and their anticipated monetary gain. The group attempted to contact Wilkinson in the days that followed.
After several unsuccessful attempts to contact him, Spurrier enlisted the aid of Wallace Wilkinson’s nephew and former employee, Bruce Wilkinson. Spurrier recorded three conversations he had with Bruce Wilkinson during which Bruce promised to talk to his uncle about meeting with the conspirators. On March 25, Bruce told Spurrier that his uncle refused to meet with Spurrier and the others. J.A. at 192.
Rogers admitted, on cross examination, that he attempted to arrange a meeting with Wallace Wilkinson to solicit a campaign contribution and to determine whether Wilkinson would follow through on his offer to give Rogers some profits from the bank. J.A. at 344, 348-49. However, Rogers denied that the offer was in any way connected to his support of the Banking Bill. J.A. at 349.
On March 31 and April 1, 1992, two FBI Special Agents interviewed Rogers. During these interviews, Rogers denied his participation in any aspect of the conspiracy or any attempt to extort money from Wilkinson. Rogers denied that Wilkinson owed him anything, that he had any agreement with Wilkinson for his support of the Banking Bill, or that he had discussed with others the amount of money owed to him by Wilkinson.
II. ANALYSIS
A. GAUDIN AND THE MATERIALITY ELEMENT OF 18 U.S.C. § 1001
Rogers was convicted on Count Four for violating 18 U.S.C. § 1001, which provides that “[w]hoever, in any matter within the jurisdiction of any department or agency of the United States knowingly and willfully ... makes any false, fictitious or fraudulent statements or representations [shall be guilty of an offense against the United States].” To establish a violation of § 1001, the government must prove that: “(1) the defendant made a statement; (2) the statement is false or fraudulent; (3) the statement is material; (4) the defendant made the statement knowingly and willfully; and (5) the statement pertained to an activity within the jurisdiction of a fеderal agency.”
United States v. Steele,
In
United States v. Gaudin,
The government points out that Rogers failed to request at trial that the jury determine the materiality element under § 1001, and did not raise it in his appellate brief. A defendant’s failure to raise an issue in the district court normally constitutes either forfeiture or waiver. “[Fjorfeiture is the failure to make the timely assertion of a right, [and] waiver is the ‘intentional relinquishment or abandonment of a known right.’”
United States v. Olano,
With respect to forfeiture, the Supreme Court recently held that where a defendant failed to object, before
Gaudin,
to the district court’s refusal to submit the issue of materiality to the jury under 18 U.S.C. § 1623 (prohibiting perjury before a grand jury), plain error review under Federal Rule of Criminal Procedure 52(b) applies.
Johnson,
at -,
We must apply the plain error doctrine to analyze the failure to submit the question of materiality to the jury.
Johnson,

Third, the defendant must prove that the error “affect[s] substantial rights.” Fed.R.Crim.P. 52(b);
Olano
at 732-36,
[i]f the investigation had been terminated without interviewing LeMaster, it would have left open the possibility that LeMaster had an innocent explanation for having accepted the money from Spurrier. If such an explanation was offerеd, the FBI had an obligation to investigate its veracity. Alternatively, the absence of a satisfactory explanation would have tended to corroborate Spurrier’s allegations.
Id. at 1231 (footnote omitted). In LeMaster, we concluded that the defendant’s false statements were “not the kind of trivial statements the materiality requirement was meant to exclude.” Id. Thus, Rogers cannot establish that the error would affect the outcome of his trial on the § 1001 charge. 5
*473
The final step in plain error analysis is to determine whether this case warrants the exercise of our discretion. The Supreme Court has emphasized that “Rule 52(b) is permissive, not mandatory” and that discretion to reverse because of plain error should be exercised оnly “in those circumstances in which a miscarriage of justice would otherwise result.”
Olano
at 735-36,
On the record before this court, we have no basis to conclude that the fairness and integrity of the proceedings below were seriously affected by the error, or that a “miscarriage of justice” will result.
See Johnson,
at -,
B. STATUTE OF LIMITATIONS
Rogers argues that the five year statute of limitations expired before the indictment was returned in this case. See 18 U.S.C. § 3282 (providing that the default statute of limitations for non-capital criminal offenses is five years from the date that the offense was committed). 6 Counts One and Two charge Rogers with conspiring and attempting to commit extortion, respectively, in violation of the Hobbs Act, under 18 U.S.C. § 1951. 7 Although Counts Three and Four charge mail fraud and perjury violations, respectively, based on acts occurring after 1992 and therefore clearly within the five year statute of limitations, Rogers contends that the entire indictment should be dismissed as time barred because each count stems from the conspiracy to pass the Banking Bill. Spurrier began cooperating with the government in January 1992. Before that date, the last overt act mentioned in the indictment occurred eight years earlier, in 1984, when the Kentucky General Assembly passed the Banking Bill. Rogers insists that the government “sidestepped” the statute of limitations by creating renewed interest in a long dead and abandoned conspiracy through Spurrier.
We reject Rogers’s argument that the government induced the continuation of an otherwise dead conspiracy. In
United States v. Tucker,
Furthermore, Rogers failed to prove that he withdrew from or abandoned the conspiracy.
See United States v. Hayter Oil Co.,
Even if Rogers had preserved the issue of withdrawal or abandonment, his claim would fail. The government proved that the conspiracy and Rogers’s participation in it, including acts of extortion and mail fraud continued into 1992. Therefore, this case differs substantially from
United States v. Walls,
C. PRE-INDICTMENT DELAY
Rogers alternatively argues that the district court erred by refusing to dismiss the indictment because the government violated his Fifth Amendment due process rights due to pre-indictment delay. The indictment was not returned until April 1994, two years after the FBI’s second interview of Rogers. During this two-year delay, in February 1994, alleged co-conspirator Frank Miller died. Rogers contends that Miller’s death caused him actual prejudice and that, since Miller’s severe health problems were widely known, the government either knew or should have known that Miller might become unavailable. Furthermore, Rogers argues that the government has offered no explanation for the delay.
Federal Rule of Criminal Procedure 48(b) provides that “[i]f there is unnecessary delay in presenting the charge to a grand jury or in filing an information against a defendant who has been held to answer to the district court, ... the court may dismiss the indictment....” Furthermore, the Supreme Court has stated that “the Due Process Clause of the Fifth Amendment would require dismissal of the indictment if it were shown at trial that ... pre-indictment delay
*475
... caused substantial prejudice to appellees’ rights to a fair trial and that the delay was an intentional device to gain tactical advantage over the accused.”
United States v. Marion,
1. Substantial Prejudice
To prove unconstitutional pre-indictment delay, the defendant must first prove “substantial prejudice to his right to a fair trial.”
United States v. Brown,
Several circuits have held that the death of a potentially material witness during an undue pre-indictment delay may prove prejudice, but that it is not alone determinative. E.g.,
United States v. Valona,
Even where a defendant specifies what a deceased witness’s testimony would have been, actual prejudice is difficult to prove. In
Valona,
the Seventh Circuit found that the death of a potential witness was insufficient to establish actual prejudice even though the defendant had suggested that the deceased could have testified as to the defendаnt’s lawful purpose in transacting business at a particular location on the date in question to controvert the government’s evidence that he was engaged in a drug transaction.
*476 In the instant case, it is not clear that the deceased Miller would have testified, especially because he invoked his Fifth Amendment right in declining to testify before the grand jury. Moreover, if Miller did testify that he was not involved in any wrongdoing relating to the Banking Bill and that the whole thing was a joke, it is unlikely that his testimony would have affected the outcome of the trial. Such testimony would seem virtually implausible in light of Miller’s statement to the FBI that he did not participate in any of the conversations recorded, the number of tape recordings in which the conspirators discussed their collection procedures, the specificity of the proof regarding the profit to be made by selling the bank in Bowling Green, and Spurrier’s testimony that the conspirators planned to extort money from Wilkinson in exchange for their support on the Banking Bill. Therefore, we agree with the district court’s conclusion that Rogers did not show actual substantial prejudice.
2. Reason for the Delay
Even if Rogers had established actual substantial prejudice, he failed to satisfy the second part of the test for unconstitutional pre-indictment delay: “that the delay was an intentional device by the government to gаin a tactical advantage.”
Brown,
Rogers argues that the government improperly delayed obtaining an indictment to gain a tactical advantage when it knew or should have known of Miller’s serious health problems. Rogers cites the testimony of Miller’s son, who stated that there were two newspaper articles about his father’s poor health when he withdrew from the race for county judge. J.A. at 297. Furthermore, Haddad testified that everybody knew Miller had health problems. J.A. at 210. Rogers asks this court to find that reckless or negligent disregard of a potentially prejudicial circumstance violates the Fifth Amendment guarantee of due process.
See United States v. Richburg,
The Assistant United States Attorneys representing the government in this case have flatly denied, under oath, that they knew that Miller was seriously ill. J.A. at 305, 422. Moreover, the government asserts that the development of a thorough and fan-investigation and the complexity of the case caused the delay in obtaining the indictment. In support of this argument, the government cites its response to Rogers’s motion to dismiss. J.A. at 55. The government does not present
sworn
testimony on the investigative reasons for the delay, nor does it describe even in a general way what investigation occurred during the two-year period between the last FBI interview of Rogers and the return of the indictment. Nonetheless, the Supreme Court has accepted such representations from counsel in this context.
See Lovasco,
Because Rogers failed to establish each element of the test, we affirm the district court’s denial of Rogers’s motion to dismiss based on pre-indictmеnt delay. 10
D. CO-CONSPIRATOR STATEMENTS
During Spurrier’s testimony, the district court admitted three tape-recorded conversations between Spurrier and Bruce Wilkinson. Rogers argued that the tapes were inadmissible hearsay, but the district court allowed the tapes into evidence under Fed. R.Evid. 801(d)(2)(E), the co-conspirator exception to the hearsay rule. Rule 801(d)(2)(E) provides that “[a] statement is not hearsay if ... [t]he statement is offered against a party and is ... a statement by a coconspirator of a party during the course and in furtherance of the conspiracy.” Rogers claims that the district court erred in that neither Spurrier nor Bruce Wilkinson were members of the conspiracy at the time the tapes were made. Spurriеr had already become an informant, and therefore according to Rogers, his statements could not have been made “during the course and in furtherance of the conspiracy” as required by Rule 801(d)(2)(E). Furthermore, Rogers claims that Bruce Wilkinson was never a member of the conspiracy, and, at most, became an “aider and abettor” by attempting to set up a meeting for the conspirators.
“In order to admit the statement of a co-conspirator under Fed.R.Evid. 801(d)(2)(E), it must first be determined that the conspiracy existed, that the defendant was a member of the conspiracy, and that the co-conspirator’s statements were made ‘in furtherance of the conspiracy.’ ”
United States v. Gesso,
Rogers correctly asserts that Spurrier was no longer a co-conspirator since he was cooperating with the government.
See United States v. Howard,
Rogers argues that the government cannot show that Bruce Wilkinson joined the conspiracy in 1992 because “a conspiracy cannot be proven by an agreement between а defendant and a government agent or informer,”
United States v. Barger,
The government need not prove that each conspirator knew every member of the conspiracy, or that each knew the full extent of the conspiracy, because such facts may be inferred from the interdependence of the enterprise.
United States v. Lloyd,
SPURRIER: Well do you remember back when we passed the banking bill?
WILKINSON: Mm Mm.
SPURRIER: We had this little arrangement with him [Wallace Wilkinson] and of course when he was governor we didn’t bring it up none.
WILKINSON: Yeah.
J.A. at 182-83. From these statements, it appears that Bruce did not know about the “arrangement” before he was enlisted in 1992 to help contact his uncle; otherwise, there would be no need to inform him about the “arrangement.” Later in the transcript, however, the conversation suggests that Bruce may have known about the conspiracy at the time the Banking Bill was passed:
SPURRIER: You were there.
WILKINSON: I was there.
SPURRIER: You saw it, hell we did everything we were supposed to.
WILKINSON: No question.
J.A. at 185. Nonetheless, Bruce Wilkinson’s mere knowledge of the existence of the agreement would not be sufficient to prove that he was a member or an agent of the conspiracy. Therefore, the district court probably erred by admitting the recordings of the three conversations between Spurrier and Bruce Wilkinson. However, we need not decide whether the district court erred by admitting the Spurrier/Bruee Wilkinson tapes because any error was harmlеss.
The erroneous admission of a statement by an unindicted co-conspirator constitutes harmless error when sufficient other evidence demonstrates a defendant’s active involvement in the conspiracy.
See United States v. Welch,
III. CONCLUSION
Thus, we reject each of Rogers’s contentions on appeal and AFFIRM his convictions in all respects.
Notes
. The conspirators referred to themselves as the "board of directors.” J.A. at 380.
.
Gaudin
overruled the case law on this issue in every circuit except the Ninth Circuit.
Gaudin,
at 526-27,
. In
Olano,
the Court explicitly left open “the special case where the error was unclear at the time of trial but becomes clear on appeal because the applicable law has been clarified.”
Id.
The Court did not contemplate the present situation, where a supervening decision reverses well-settled controlling case law.
Johnson,
however, appears to have filled in the answer.
See United States v. Barone,
. Rogers contends that he was faced with a "catch 22” situation in that he could either answer truthfully, which would amount to a confession of the crimes charged, or lie, which would result in an additional felony charge for perjury. The Sixth Circuit has explicitly rejected this type of "catch 22” argument.
See Steele,
. Though we believe that the failure to submit the issue of materiality to a jury could constitute "structural error,”
see,
e.g.,
Sullivan v. Louisiana,
. Section 3282 states:
Except as otherwise expressly provided by law, no person shall be prosecuted, tried, оr punished for any offense, not capital, unless the indictment is found or the information is instituted within five years next after such offense shall have been committed.
. Section 1951 provides in pertinent part:
(a) Whoever in any way or degree obstructs, delays, or affects commerce or the movement of any article or commodity in commerce, by robbery or extortion or attempts or conspires so to do, or commits or threatens physical violence to any person or property in furtherance of a plan or purpose to do anything in violation of this section shall be fined under this title or imprisoned not more than twenty years, or both.
(b) As used in this section—
* *
(2) The term “extortion” means the obtaining of property from another, with his consent, inducеd by wrongful use of actual or threatened force, violence, or fear, or under color of official right.
. Moreover, Rogers conceded that an overt act is not required to establish a conspiracy to violate the Hobbs Act. Appellant's Brief, at 18. At least one case in this circuit has suggested that proof of an overt act is required to establish a violation of 18 U.S.C. § 1951.
United States v. Benton,
. The district court also found that other members of the alleged conspiracy could have testified on Rogers's behalf as to the nature of the alleged co-conspirators' actions. J.A. at 95-96. However, the only other member of the conspiracy whom Rogers realistically could have called in Miller's place was William Wester, because Spurrier testified as a government informant and Wilkinson was not present for the meetings during which the other conspirators discussed how to contact him.
. The standard for pre-indictment delay is nearly insurmountable, especially because proof of actual prejudice is always speculative.
See United States v. Mays,
. To the extent that Rogers is arguing that Spurrier's portion of the conversations should have been excluded, he should have asked for a limiting instruction pursuant to Fed.R.Evid. 105, as in Howard. See id.
. “Grubstake” is defined as "[s]upplies or funds advanced to a mining prospector or a person *479 starting a business in return for a promised share of the profits.” The American Heritage Dictionary, at 579 (2d ed.1982).
