OPINION OF THE COURT
Michael Walker appeals his sentence from a conviction in the United States District Court for the Middle District of Pennsylvania for numerous firearms, robbery and drug charges. At issue is whether the 55-year consecutive mandatory minimum portion of his sentence on the firearms charges violates the Fifth and Eighth Amendments to the Constitution. We have jurisdiction pursuant to 18 U.S.C. § 3742 and 28 U.S.C. § 1291. We will affirm.
I.
Superceding Indictment No. 03-93 charged Walker with offenses arising from the armed robbery of the Mr. Z’s Food Mart in Hawley, Pennsylvania on October 26, 2001; the armed robbery of the Peoples National Bank in Nicholson, Pennsylvania on November 30, 2001; and the sale of cocaine, cocaine base (“crack”), and marijuana in Scranton, Pennsylvania be *74 tween October 2001 and September 28, 2002. Walker was charged with two counts in connection with the Mr. Z’s robbery: interference with commerce by robbery, in violation of 18 U.S.C. § 1951 (Count I) and using and possessing a short-barreled Harrington and Richardson 12 gauge shotgun during and in relation to a crime of violence, in violation of 18 U.S.C. § 924(c) (Count II). On October 26, 2001, Walker robbed two employees of Mr. Z’s who were on their way to make a night deposit at a bank in the same strip mall. Walker demanded the deposit bag from the employees, told the employees to run, and fired a shot from his short-barreled shotgun. He made off with $9,628.21 in cash and $14,698.87 in checks, receipts and coupons.
The Superceding Indictment also charged Walker with two counts in connection with the Peoples National Bank robbery: armed bank robbery, in violation of 18 U.S.C. § 2113(d) (Count III) and using, carrying and brandishing a short-barreled Harrington and Richardson 12 gauge shotgun and a silver Bryco .380 automatic handgun during and in relation to the crime of armed bank robbery, in violation of 18 U.S.C. § 924(c) (Count IV). On November 30, 2001, Walker used both the sawed-off shotgun and the handgun to rob the Peoples National Bank. He pointed the shotgun in the faces of employees of the bank, and threw a 92-year-old man to the ground when the man did not respond to his commands. He obtained $8,863 from the bank robbery. The Superceding Indictment also charged Walker with one count of possession of an unregistered short-barreled Harrington and Richardson 12 gauge shotgun between October 2001 and February 2002, in violation of 26 U.S.C. §§ 5841, 5861(d) and 5871 (Count V).
In addition to the robbery and firearms charges, the Superceding Indictment charged Walker with four counts related to his sales of cocaine, cocaine base (“crack”), and marijuana from his home in Scranton, Pennsylvania: conspiracy to distribute and possess with intent to distribute in excess of 50 grams of cocaine base (“crack”), cocaine, and marijuana between October 2001 and September 28, 2002, in violation of 21 U.S.C. § 846 (Count VI); distribution of cocaine base (“crack”) and aiding and abetting the distribution of cocaine base (“crack”) between October 2001 and September 27, 2002, in violation of 21 U.S.C. § 841(a)(1) and 18 U.S.C. § 2 (Count VII); possession with intent to distribute in excess of five grams of cocaine base (“crack”) and aiding and abetting the possession with intent to distribute in excess of five grams of cocaine base (“crack”) on September 28, 2002, in violation of 21 U.S.C. § 841(a)(1) and 18 U.S.C. § 2 (Count VIII); and possession of a Jennings .9mm pistol during and in relation to a drug trafficking offense on September 28, 2002, in violation of 18 U.S.C. § 924(c) (Count IX). In connection with these drug trafficking offenses, Walker distributed and possessed with intent to distribute 100 grams of cocaine base and 1 kilogram of cocaine and supervised the distribution of these drugs by another individual.
The drug trafficking charges (Counts VI-IX) were severed from the armed robbery and armed bank robbery charges (Counts I-V) for trial. On March 12, 2004, Walker was convicted by a jury of Counts VI-IX. On September 29, 2004, Walker was convicted by a jury of Counts I-V.
Walker was sentenced on June 16, 2005. He objected to the pre-sentence report on the grounds that the consecutive mandatory minimum sentences totaling 55 years of imprisonment for the three violations of 18 U.S.C. § 924(c), Counts II, IV and IX, *75 were unconstitutional. 1 The District Court overruled his objections and sentenced him to a term of imprisonment of 65 years, consisting of 120 months on each of Counts I, III, V, VI, VII, and VIII, to be served concurrently; 2 and to mandatory minimum terms of imprisonment of five years on Count IX, to be served consecutively to the term of imprisonment imposed for Counts I, III, V, VI, VII and VIII; and 25 years on each of Counts II and IV, to be served consecutively to each other and to the terms imposed for Counts I, III, V, VI, VII, VIII, and IX. The District Court also sentenced Walker to a total term of supervised release of five years, a special assessment of $900, and restitution in the amount of $24,004.72, to be paid to Mr. Z’s Food Mart and to Peoples National Bank. 3
II.
Walker asks us to find that his consecutive mandatory minimum sentence of 55 years of imprisonment pursuant to 18 U.S.C. § 924(c)(1) is unconstitutional because it violates the Due Process Clause of the Fifth Amendment and the doctrine of separation of powers; constitutes an irrational classification in violation of the equal protection principles of the Fifth Amendment; inflicts cruel and unusual punishment in violation of the Eighth Amendment; and was not appropriate under established rules of statutory construction. The standard of review for Walker’s constitutional challenge to his mandatory minimum sentence is plenary, as is his statutory construction challenge.
See United States v. Randolph,
III.
Walker contends that the mandatory consecutive sentencing scheme of Section 924(c)(1) violates the Due Process Clause of the Fifth Amendment and the doctrine of separation of powers because it limits the court’s discretion at sentencing and turns that discretion over to the executive branch.
See Mistretta v. United
*76
States,
This Court has squarely addressed and rejected the argument that mandatory sentences violate the doctrine of separation of powers and the Due Process Clause.
See United States v. MacEwan,
IV.
Walker also argues that his 55-year mandatory consecutive sentence for violations of Section 924(c)(1) is irrational when compared with the punishment for other, more serious federal crimes and, therefore, violates the equal protection principles of the Due Process Clause.
See Mathews v. de Castro,
Under rational basis review, “a classification must be upheld against equal protection challenge if there is any reasonably conceivable state of facts that could provide a rational basis for the classification.”
Id.
at 320,
Walker argues that Section 924(c)(1) is intended to punish the potential for violence created by the carrying of a firearm in the prohibited circumstances and that it is irrational to punish the potential for violence more harshly than actual violent crime. He asks us to compare the sentence he received in this case, for three violations of Section 924(c), with the sentences recommended by the Sentencing Guidelines for other, actually violent, crimes such as an aircraft hijacking, a terrorist bombing, and a racially motivated assault with attempt to kill. Assuming that Walker’s hypothetical violent criminals had no prior adult criminal convictions, his airline hijacker would have a total offense level of 38, a criminal history category of I, and an advisory Guidelines sentencing range of 235-293 months pursuant to U.S.S.G. § 2A5.1 and Part 5A; his terrorist bomber would have a total offense level of 36 and a criminal history category of VI, and face an advisory Guidelines sentencing range of 324-405 months pursuant to U.S.S.G. § 2K1.4(a), § 3A1.4(a) and (b) and Part 5A; and his racist attempted murderer would have a total offense level of 40, a criminal history category of I, and an advisory Guidelines sentencing range of 292-365 months pursuant to U.S.S.G. § 2A2.1(a), § 2A2.1(b)(l)(A), § 3Al.l(a), and Part 5A. Walker’s hypotheticals do not take into account the fact that a defendant who commits three such violent crimes could be subject to a term of imprisonment at least as long as the one imposed on Walker. Thus, Section 924(c)(1) did not irrationally punish the potential for violence posed by Walker’s use of a firearm in connection with two crimes of violence and one drug trafficking crime more than he might have been punished for “actual” violent crime.
Walker also argues that Section 924(c)(1) is irrational because it fails to differentiate between a first time offender who commits more than one Section 924(c)(1) offense and a recidivist. Consequently, he contends that he is being punished as a recidivist even though he has not “failed to learn his lessons from the initial punishment” and committed a repeat offense. The Supreme Court has rejected the contention that the second or consecutive sentencing provision of Section 924(c)(l)(C)(i) could only rationally apply to “recidivists.”
See Deal v. United States,
We choose to follow the language of the statute, which gives no indication that punishment of those who fail to learn the “lesson” of prior conviction or of prior punishment is the sole purpose of § 924(e)(1), to the exclusion of other penal goals such as taking repeat offenders off the streets for especially long periods, or simply visiting society’s retribution upon repeat offenders more severely. We do not agree with the dissent’s suggestion that these goals defy “common sense.” It seems to us eminently sensible to punish the second murder, for example, with life in prison rather than a term of years-whether or not conviction of the first murder (or completion of the sentence for the first murder) has yet occurred.
Deal,
The Government urges us to conclude that Congress’s decision to classify and punish repeat violators of Section 924(c)(1) more harshly than one-time offenders is rationally related to the legitimate governmental interest in discouraging the use of firearms in violent crimes and drug trafficking crimes and in punishing more harshly criminals who repeatedly use deadly weapons. Congress’s “overriding purpose” in passing Section 924(c) “was to combat the increasing use of guns to commit federal felonies.”
Simpson,
Section 924(c) has been amended several times. In the Comprehensive Crime Control Act of 1984, Congress “eliminat[ed] the range of permissible penalties, set[ ] a mandatory prison term of five years,” for use or carrying of a firearm during or in relation to a crime of violence, “and specified] that that term was to be added on top of the prison term related to the underlying ‘crime of violence,’ including statutory sentences that imposed certain other weapons-related enhancements.”
Castillo v. United States,
This Court has previously recognized that, in imposing the mandatory consecutive sentences for second or subsequent offenders in Section 924(c)(1), “[i]t is likely that Congress meant ... to protect our communities from violent criminals who repeatedly demonstrate a willingness to employ deadly weapons by punishing them more harshly.”
United States v. Couch,
V.
Walker further argues that his sentence violates the Eighth Amendment’s prohibition on cruel and unusual punishment because (1) it is grossly disproportionate to the offenses that he committed and (2) it is contrary to the evolving standards of decency that are the hallmark of our civilized society. The Supreme Court has long recognized that “[t]he Eighth Amendment, which forbids cruel and unusual punishments, contains a ‘narrow proportionality principle’ that ‘applies to noncapital sentences.’ ”
See Eimng v. California,
*80
In
Rummel v. Estelle,
One of those exceedingly rare successful cases was
Solem v. Helm,
In
Harmelin v. Michigan,
Walker argues that his sentence is grossly disproportionate to his offense in violation of the Eighth Amendment in accordance with the proportionality factors set forth in Solem. He contends that the first factor is satisfied because his Guidelines sentence for the drug and robbery convictions is sufficient to punish all of his crimes and that the involvement of guns in those crimes does not warrant increasing his sentence by 55 years of imprisonment. He further argues that a comparison of his sentence and the sentences for other serious federal crimes shows that his sentence is extreme and satisfies the second factor. He also maintains that it is common knowledge that the 55-year sentence which he received for his violations of Section 924(c)(1) is far more severe than he would have received in other jurisdictions, satisfying the third factor.
This Court recently examined the application of the
Solem
factors in light
*82
of
Harmelin
and
Ewing. See MacEwan,
The Government argues that Walker’s sentence is not grossly disproportionate to his crime because, as is confirmed by the evidence admitted at his trials, Walker is a violent criminal who repeatedly committed serious crimes and armed himself with firearms as a tool of his drug trade and to facilitate his robberies. He used a short-barreled shotgun to commit the Mr. Z’s Food Mart robbery and discharged the shotgun during that robbery. He used the same shotgun, as well as a pistol, during the Peoples National Bank robbery, leveling the shotgun at tellers’ heads and throwing a 92-year-old man to the ground. He later used a semi-automatic pistol in connection with drug dealing. The Government maintains that, in light of Walker’s egregious, repeated conduct, the consecutive mandatory minimum sentences totaling 55 years imposed for his three violations of Section 924(c)(1) are not grossly disproportionate to his crimes.
We are guided in our analysis of Walker’s proportionality challenge to his 55-year mandatory consecutive sentence by the requirement that we “grant substantial deference to the broad authority that legislatures necessarily possess in determining the types and limits of punishments for crimes.”
See MacEwan,
Walker also asks us to consider whether our nation’s evolving standards of decency require us to find that his sentence consti *84 tutes cruel and unusual punishment. Walker relies on the recommendation of the 2004 ABA Justice Kennedy Commission that federal and state governments repeal mandatory minimum sentences. American Bar Association Justice Kennedy Commission, Reports with Recommendations to the ABA House of Delegates, dated August, 2004, at 9, available at http://www.abanet.org/crimjust/kennedy/ Justice KennedyCommissionReportsFi-nal.pdf. Walker also suggests that the imposition of a 55-year prison term on a first-time offender cannot encompass rehabilitation but, rather, denies both the offender and the community a second chance.
We find that, rather than violate our evolving standards of decency, Walker’s mandatory consecutive sentences represent Congress’s attempt to address the serious societal problem of the use of firearms in connection with violent crimes and in connection with drug trafficking.
See Muscarello,
VI.
Walker also argues that his harsh mandatory consecutive sentence could have been avoided had the District Court utilized the appropriate principles of statutory construction. He contends that the minimum term of 25 years of imprisonment for a second or subsequent felony conviction for use of a firearm in connection with a crime of violence or a drug trafficking crime mandated by Section 924(c)(l)(C)(i) directly conflicts with the controlling mandate of 18 U.S.C. § 3553(a) that a court shall “impose a sentence sufficient, but not greater than necessary, to comply with the purposes set forth in paragraph (2) of this subsection.” 7 18 U.S.C. § 3553(a).
Walker asserts that the district court could have avoided imposing his draconian mandatory sentence by imposing a sentence which met the sentencing goals of 18 U.S.C. § 3553(a), rather than the severe consecutive mandatory minimum sentences required by Section 924(c)(1). He maintains that it is an established rule of statutory construction that criminal laws are to be strictly construed in favor of the defendant and that the district court should have chosen “the construction yielding the shorter sentence by resting on the venerable rule of lenity, rooted in ‘the instinctive distaste against men languishing in prison unless the lawmaker has clearly said they should.’ ”
United States v. R.L.C.,
We perceive no doubt about the intended scope of Section 924(c)(1). The Supreme Court has explained that this statute requires the imposition of the mandatory consecutive second or subsequent offense penalties of Section 924(c)(l)(C)(i) to a defendant, such as Walker, who has been convicted of multiple counts of violating Section 924(c)(1) which were charged in the same indictment.
See Deal,
For the reasons set forth above, we reject Walker’s constitutional and statutory construction challenges to his 55-year consecutive mandatory minimum sentence and affirm the sentence imposed by the District Court.
Notes
.Title 18, United States Code, Section 924(c) provides that the mandatory minimum term of imprisonment for possession of a firearm during and in relation to a crime of violence or a drug trafficking offense is five years. 18 U.S.C. § 924(c)(l)(A)(i). If the firearm is a short-barreled shotgun, the mandatory minimum term of imprisonment is ten years. 18 U.S.C. § 924(c)(l)(B)(i). If the defendant is being sentenced for a second or subsequent conviction of Section 924(c), the mandatory minimum term of imprisonment is 25 years. 18 U.S.C. § 924(c)(l)(C)(i). Section 924(c)(l)(C)(i) applies even if the second or subsequent conviction is for a count charged in the same indictment as the initial violation of Section 924(c).
See Deal v. United States,
. Walker’s sentence for these offenses is less than the advisory Guidelines sentencing range. Walker had a total offense level of 34 for Counts I, III, V, VI, VII and VIII and a criminal history category of I. The advisory Guidelines sentencing range for a total offense level of 34 and a criminal history category of I is 151-188 months. See U.S.S.G. Part 5A.
. Walker was ordered to pay restitution in the amount of $18,541.72 to Mr. Z's Food Mart and $5,463.00 to Peoples National Bank. Walker had paid James Harris, who drove the getaway car from the Peoples National Bank robbery, $3,400 from the proceeds of that robbery. Harris, who was also convicted in the robbery, was ordered to pay restitution to Peoples National Bank in the amount of $3,400 as part of his sentence.
