Opinion for the Court filed by Circuit Judge GARLAND.
Defendant Marc Weathers was found guilty on all counts of a six-count indictment arising out of his attempts to arrange for the murder of several witnesses and a prosecutor. He contends that two of his six convictions should be vacated because each charges an offense also included in the remaining four counts. We conclude that defendant waived this claim by failing to raise it before trial. We find that defendant’s further contention, that his attorney provided ineffective assistance by failing to assert this claim in a timely manner, must be remanded to the district court for an initial determination.
I
In a case filed in the Superior Court of the District of Columbia in 1996, Assistant United States Attorney (AUSA) Bernadette Sargeant obtained an indictment charging Weathers with thirty-seven counts of rape and related offenses involving five victims, including a thirteen-year-old child. 1 The presiding judge ordered the five rape cases severed for separate trials. Prior to trial on the first rape case, *950 an informant told Sargeant that defendant had plotted to kill the five victims to prevent them from testifying. The trial was postponed, and after investigation Sar-geant obtained a second Superior Court indictment charging Weathers with two counts of obstruction of justice.
In March 1997, just weeks before the rescheduled rape trial was set to begin, a second informant told the FBI that Weathers was trying to hire him to arrange the killing of. both the rape victims and the prosecutor. At the government’s request, the informant met with Weathers and recorded a conversation in which defendant said he would pay $1,000 in advance and $19,000 after AUSA Sargeant was killed. The plan required the informant to hire a hit man, and provided that defendant’s friend on the outside, Maurice Logan, would make the necessary payments. 9/30/97 Tr. at 6-8,10-11, 15-19.
On March 19, 1997, Detective Larry Best of the Metropolitan Police Department, posing as a hit man, met with Weathers in jail and discussed the details of the murder-for-hire scheme. Weathers instructed Detective Best that he should first kill the victim in the upcoming trial, who lived on Hayes Street. “I need Hayes done first,” defendant said. App. 19; 9/29/97 Tr. at 138-40. “Maybe you can blow that [expletive deleted] up.” App. 23. With respect to AUSA Sargeant, whom he referred to as the “DA,” Weathers first said that killing her “ain’t gonna do nothing but slow the proces[s] ... cause see if she gone they just put another one in.” Id. at 19. Later, however, defendant said: “I just want her gone. You know what I’m saying. I just want ’em gone. Set an example.... I don’t really got no ... special way. I just want it done. You know what I’m saying. Easiest way for you.” Id. at 20, 22. Weathers told Best that he could get his payment for the killings from Weathers’ friend Logan and a woman named Mattie. Id. at 15-19.
On March 26, 1997, the FBI conducted a search of Maurice Logan’s apartment, in which it found a letter from defendant dated March 9. 9/29/97 Tr. at 150-53. In that letter, Weathers urged Logan to burn down the witnesses’ homes to keep them from testifying. The letter read, in part:
[Tjhese people are trying to give me life without parole, and we both know I can’t do that number, so I need you to get at a couple of these bitches for me. You don’t have to kill them, just burn they house down while they in it, or something, so they won’t come to court. You know if the situation was reversed, I’d do it for you.... [T]hey don’t have a case without these bitches, and they ain’t going to spend no money hiding everybody.
Id. at 180-81.
On April 22, 1997, Weathers was indicted in United States District Court for plotting against the witnesses and prosecutor in his Superior Court cases. The indictment charged him with: (1) using facilities of interstate commerce in the commission of murder-for-hire, in violation of 18 U.S.C. § 1958; (2) threatening to injure a person (the rape victims), in violation of D.C. Code § 22-2307; (3) obstructing justice (based on the threats against the rape-victim witnesses), in violation of D.C. Code § 22-722(a)(6); (4) threatening a federal official (AUSA Sargeant), in violation of 18 U.S.C. § 115; (5) threatening to injure a person (Sargeant), in violation of D.C. Code § 22-2307; and (6) obstructing justice (based on the threats against Sar-geant), in violation of D.C. Code§ 22-722(a)(6). App. 11-14. 2 The defendant was convicted on all counts, and was sentenced to: (1) ten years imprisonment on Count One; (2) 80-240 months on each of Counts Two and Five; (3) fifteen years to life on both Counts Three and Six; and (4) *951 five years imprisonment on Count Four. The court ordered Counts Two, Three, Five, and Six to run consecutive to each other, but concurrent with consecutive sentences on Counts One and Four.
II
Defendant contends that his indictment charged the same offense in more than one count, a problem known as “multiplicity.”
See
1A ChaRles Alan Wright, Federal Practice & Procedure §§ 142, 145, at 7-8, 86 (3d ed.1999). Because the Double Jeopardy Clause protects not only against “a second prosecution for the same offense” after acquittal or conviction, but also against “multiple punishments for the same offense,”
North Carolina v. Pearce,
Defendant’s first contention is that his conviction on Count Four for threatening a federal official (AUSA Sargeant) in violation of 18 U.S.C. § 115, and his conviction on Count Five for threatening to injure a person (also Sargeant) in violation of D.C.Code § 22-2307, constitute two convictions for the same offense. To determine whether Congress intended two statutory provisions to proscribe the same offense, the Supreme Court has applied the rule set forth in
Blockburger v. United States:
“[Wjhere the same act or transaction constitutes a violation of two distinct statutory provisions, the test to be applied to determine whether there are two offenses or only one, is whether each provision requires proof of a fact which the other does not.”
Section 115(a) makes it a crime to “threaten! ] to assault, kidnap, or murder, a United States official, ... with intent to impede, intimidate, or interfere with such official, ... while engaged in the performance of official duties....” D.C.Code § 22-2307 makes it a crime, within the District of Columbia, to “threaten! ] ... to injure the person of another.” As is apparent from a reading of the two statutes, some facts required to prove Count Four are not required to prove Count Five (for example, that the threatened person is “a United States official” and that the threat was made with “intent to impede”). Defendant contends, however, that there is no fact required to prove Count Five that is not also required to prove Count Four. If true, this would make the local crime charged in Count Four the equivalent of a “lesser included offense” of the federal crime charged in Count Five. Therefore, an indictment charging both would fail the
Blockburger
test.
See Rutledge,
The government disputes this conclusion. It contends that the D.C. statute does have an additional element not contained in the federal statute. Pointing to model jury instructions for D.C.Code § 22-2307, and to
United States v. Baish,
Defendant’s second contention is that we must vacate either his conviction on Count Three, for violating D.C.Code § 22-722(a)(6) by obstructing justice based on the threats he made against the rape-victim witnesses, or his conviction on Count Six, for violating the same statute based on the threats he made against Sargeant. He argues that these also constitute a single offense. Where two violations of the same statute rather than two violations of different statutes are charged, courts determine whether a single offense is involved not by applying the
Blockburger
test, but rather by asking what act the legislature intended as the “unit of prosecution” under the statute.
See Sanabria v. United States,
D.C. Code § 22-722(a)(6) provides that [a] person commits the offense of obstruction of justice if that person [c]or-ruptly, or by threats of force, any way obstructs or impedes or endeavors to obstruct or impede the due administration of justice in any official proceeding.
Defendant contends that the unit of prosecution intended by the statute is an “official proceeding,” and hence that any number of threats against any number of witnesses on any number of occasions may be charged only once, as long as they all relate to a single such proceeding. The government responds by asserting that the District of Columbia Court of Appeals has routinely permitted multiple convictions for obstruction of justice (albeit under a different subsection of the statute), where the defendant has impeded multiple witnesses in a single trial.
See
Gov’t Br. at 22 (citing
Skyers v. United States,
Ill
Although it denies that its indictment is multiplieitous, the government argues that we need not resolve the merits of defendant’s multiplicity challenges because he failed to raise them before trial, or at any time prior to this appeal. We agree. Rule 12(b)(2) of the Federal Rules of Criminal Procedure states:
Any defense, objection, or request which is capable of determination without the trial of the general issue may be raised before trial by motion.The following must be raised prior to trial: ... Defenses and objections based on defects in the indictment or information ....
Fed.R.CeimP. 12(b)(2). Rule 12(f) provides that “[fjailure by a party to raise defenses or objections or to make requests which must be made prior to trial ... shall constitute waiver thereof, but the court for cause shown may grant relief from the waiver.” Fed.R.CRIM.P. 12(f). According to Circuit precedent, multiplicity claims of the kind presented here are defenses based on “defects in the indictment” within the meaning of Rule 12(b)(2), and hence are waived under Rule 12(f) if not raised prior to trial. This means that unless “cause” is shown, they “may not later be resurrected” on appeal.
Davis v. United States,
In
United States v. Harris,
In reaching this result, Harris expressly rejected the argument “that a multiplicity objection is not included within the defects contemplated by Rule 12(b)(2), because it is a defect in the sentencing, not in the indictment.” Id. To the contrary, the court held that “if the multiplicity objection could have been raised based on the indictment, Rule 12(b)(2) applies.” Id. “The purpose of the rule,” Harris said, “is to compel defendants to object to technical defects in the indictment early enough to allow the district court ... to permit the prosecution to accommodate meritorious challenges, and to do so without disrupting an ongoing trial.” Id. The court then quoted extensively from the Supreme Court’s opinion in Davis v. United States, which identified the same underlying purpose for the waiver provision of Rule 12:
If [Rule 12(b)(2)] time limits are followed, inquiry into an alleged defect may be concluded and, if necessary, cured before the court, the witnesses, and the parties have gone to the burden and expense of a trial. If defendants were allowed to flout its time limitations, on the other hand, there would be little incentive to comply with its terms when a successful attack might simply result in a new indictment prior to trial. Strong tactical considerations would militate in favor of delaying the raising of the claim in the hopes of an acquittal, with.the thought that if those hopes did not materialize, the claim could be used to upset an otherwise valid conviction at a time when reprosecution might well be difficult.
Id.
(quoting
Davis,
Two years later, in
United States v. Clarke,
*954
This case is on all fours with
Harris
and
Clarke.
Weathers challenges his convictions on multiplicity grounds; he makes both the two-statutes-charge-one-offense claim considered in
Hams
and the single-statute-charges-only-one-offense claim reviewed in
Clarke.
Like defendants Harris and Clarke, Weathers did not object before trial. And as in
Harris
and
Clarke,
the alleged defect appears on the face of the indictment — a point which defendant concedes and upon which he even insists,
see
Def. Br. at 20; Reply Br. at 8, 11, 18.
5
Counts Four and Five expressly charge Weathers with threatening the same person (Sargeant) during the same túne period, and specifically list the two statutes assertedly violated. App. 13. Since a
Blockburger
claim focuses exclusively on the statutory elements of the offenses,
see United States v. White,
The “spirit of the rule” identified in
Hams
is also consistent with a finding of waiver in this ease.
See Harris,
In his reply brief, defendant urges us not to follow
Hams,
contending that the Supreme Court’s subsequent decision in
United States v. Olano,
Weathers contends that the failure to raise a multiplicity (or any other) claim before trial cannot by itself amount to the intentional relinquishment of a known right. Thus, he argues, that failure must be considered a forfeiture and not a waiver. From this he concludes that Olano requires that his appeal be reviewed for plain error — effectively overturning Harris’ holding that a failure to come within Rule 12(b)(2)’s time limits results in the waiver of any claim covered by that Rule.
We cannot agree that
Harris
has been annulled by
Olano.
First, we have continued to apply
Harris
to multiplicity claims even after
Olano
was decided in 1993.
See Clarke,
Second, Olano itself recognized that there is a difference between waiver and forfeiture. While Rule 52(b) does not mention “waiver,” Rule 12(f) expressly does. Yet, on defendant’s reading, the waiver language of Rule 12(f) would add nothing to the forfeiture principle of Rule 52(b). Defendant’s “waiver” of his multiplicity claim under Rule 12(f) would have no consequence other than that it would be reviewed for plain error, the same result as if there were no Rule 12(f). We cannot conclude that the Supreme Court intended to render Rule 12(f) a nullity in a decision that did not even mention it.
Finally, although in the context of its discussion of Rule 52(b)
Olano
said that waiver is the “intentional relinquishment or abandonment of a known right,” the Court also noted that “whether the defendant’s choice must be particularly informed or voluntary ... depend[s] on the right at stake.”
Olano,
Davis
involved a postconviction attack on a defendant’s indictment, based on the allegation that there had been unconstitutional discrimination in the selection of the grand jury that issued it.
The Court, however, did not agree. It conceded that defendant had alleged the deprivation of a “substantial constitutional right,”
id.
at 243,
*957 In sum, Olano and Davis (and therefore Harris) are not inconsistent with each other. Although Olano indicates that untimely objections are generally regarded as forfeitures subject to Rule 52(b), Davis dictates that untimely objections that come within the ambit of Rule 12(b)(2) must be considered waivers and may not be revived on appeal. We cannot conclude that the Court intended Olano, a case which mentioned neither Rule 12 nor Davis, to overrule Davis by redefining sub silentio the meaning of the word “waiver” in Rule 12. 12
Finally, defendant seeks some support for his position in the
post-Davis,
pre-
Olano
case of
United States v. Broce,
Defendant focuses on the fact that
Broce
distinguished an earlier case,
Menna v. New York,
In sum, Harris and Davis continue to guide our course here. Together, they compel the conclusion that defendant has waived his multiplicity claims by failing to raise them before trial.
IV
Defendant contends that his trial counsel’s failure to raise his multiplicity claims in a timely manner constituted ineffective assistance under
Strickland v. Washington,
A
Strickland
claim has two components. First, “the defendant must show that counsel’s performance was deficient.”
Notwithstanding the argument made in his reply brief, at oral argument defendant conceded that his trial counsel’s failure to raise the multiplicity claims before trial might have been predicated on a tactical choice. As discussed in Part III, had defense counsel raised the claims pretrial, not only might the defects have been repaired,
see supra
note 6, they might have been repaired by increasing the number of counts arrayed against defendant,
see supra
page 11. Faced with that possibility, defense counsel might well have opted to leave the indictment as it stood rather than risk making matters worse for his client. Recognizing that defense counsel’s silence may therefore have represented a strategic decision, at oral argument defendant changed course and joined the government in requesting a remand of his ineffective assistance claim for initial determination by the district court. That is clearly the proper disposition of this issue.
See Fennell,
V
For the foregoing reasons, we hold that defendant has waived his multiplicity claims. His charge of ineffective assis *959 tance of counsel is remanded to the district court.
Notes
. The United States Attorney’s Office for the District of Columbia prosecutes offenses in both the United States District Court and the local Superior Court.
See United States v. Brooks,
. Federal and District of Columbia offenses may be charged in the same indictment and prosecuted in the United States District Court for
the District of
Columbia. D.C.Code § 11-502(3);
see United States v. Sumler,
. Although the Double Jeopardy Clause does not bar multiple punishments under federal and state law, a defendant may not be punished twice for the same offense under both the United States Criminal Code and the Dis-tact of Columbia Criminal Code because both were adopted by Congress.
See Sumler,
. In
United States v. Anderson (Anderson I),
. Defendant insists that the multiplicity violation is clear on the face of the indictment as support for his argument that it constitutes plain error under Fed.R.Crim.P. 52(b). See discussion infra pp. 954-55.
. Counts Three and Six each charged Weathers with impeding two proceedings, the original (unsevered) Superior Court rape case and the Superior Court obstruction case. App. 12-14. Hence, as the government contends, if defendant had timely objected, any multiplicity problem might have been repairable through a bill of particulars stating that each count referred to a different Superior Court case. The fact that the problem was curable, however, does not take it outside the scope of Rule 12(b)(2). To the contrary, the purpose of the Rule is to ensure that "inquiry into an alleged defect may be concluded and, if necessary, cured.”
Davis,
. Rule 52(b) states: "Plain errors or defects affecting substantial rights may be noticed although they were not brought to the attention of the court.”
. Although
Clarke
did not discuss
Olano
and Rule 52(b) in the course of finding defendants’ multiplicity claim barred by waiver, it did discuss both in deciding that another of defendants’ claims was governed by the plain error standard.
See Clarke,
.
Kaufman
was subsequently overruled in
Stone v. Powell,
. At the time the Court decided Davis, the waiver provision now in Rule 12(f) was contained in Rule 12(b)(2) itself. See Fed. R.Ceim.P. 12(b)(2) (1971).
. Defendant cites the
pre-Davis
case of
Green v. United States,
Green
does not assist defendant in the instant case. Unlike the provision in Rule 12 that expressly makes the failure to timely object a waiver, there is no rule that makes the filing of an appeal a waiver. Nor is there any logical reason to regard an appeal as a waiver. Rather, as the Court ultimately concluded, the notion that an appeal constitutes a waiver was nothing more than the "wholly fictional” construct of government counsel.
Id.
at 192,
. Of course, even if we thought it did, it is not for the lower courts to conclude that the Supreme Court’s "more recent cases have, by implication, overruled an earlier precedent.”
Agostini v. Felton,
. Defendants' trial counsel submitted an affidavit stating that he had not discussed his clients' Double Jeopardy rights with them, nor had his clients considered the possibility of raising that defense before entering their plea.
Id.
at 572-73,
. Indeed, unlike a claim of multiplicity, a claim of former jeopardy like that at issue in
Menna
may not fall within Rule 12(b)(2) at all.
