Opinion for the Court filed by Circuit Judge GINSBURG.
A jury found Lewis McCarson guilty of being a felon in possession of a firearm, see 18 U.S.C. § 922(g)(1), and of possessing with the intent to distribute five grams or more of cocaine base, see 21 U.S.C. § 841(a)(1) & (b)(1)(B)(iii). He was acquitted of possessing a firearm during a drug-trafficking offense, see 18 U.S.C. § 924(c)(1), and of possessing with the intent to distribute marijuana, see 21 U.S.C. § 841(a)(1) & (b)(1)(D). On appeal, McCarson argues that evidence of the gun and the drugs, which the U.S. Marshals discovered while executing a warrant for McCarson’s arrest in connection with another charge, should be suppressed as the fruits of an unreasonable search in violation of the Fourth Amendment to the Constitution of the United States. In addition, McCarson contends the district court erroneously applied Rules 404(b) and 403 of the Federal Rules of Evidence in allowing the Government to introduce evidence of his prior convictions. We find merit in neither argument and therefore affirm the conviction.
I. Background
Having learned from a reliable source that McCarson was staying at his girlfriend’s apartment in the District of Columbia, Deputy U.S. Marshals went to her apartment early one morning with a war *172 rant for his arrest. McCarson answered the door wearing boxer undershorts and a t-shirt and holding an infant in his arms. The Marshals, who recognized him from a photograph, directed McCarson to sit at the kitchen table, which he did, and conducted a protective sweep of the two-bedroom apartment, in the course of which they discovered nothing of concern. In preparation for his arrest, McCarson made a telephone call to ensure that somebody would take custody of the child and said he wanted to wear his black pants, coat, and shoes, which were in one of the bedrooms. A Marshal told McCarson to remain seated, and two other Marshals went into the bedroom to get those articles. In the process of retrieving them, one of the Marshals noticed marijuana in an open drawer of a dresser inches away from him and then saw an automatic handgun in another drawer, which was also ajar; the latter drawer also contained crack cocaine, which the district court found to have been in plain sight either from the outset or once the Marshals removed the gun.
II. Analysis
On appeal, McCarson argues first that the gun and narcotics should have been suppressed under the Fourth Amendment. In
Payton v. New York,
McCarson’s argument that the evidence should have been excluded from his trial finds no support in
Steagald.
There the police, who had obtained a warrant for the arrest of one Lyons, learned from an informant that Lyons was staying at a certain address, which turned out to be the residence of one Steagald. The police searched Steagald’s home but, instead of Lyons, found narcotics. The Supreme Court held the drugs were inadmissible as against the householder, Steagald,

McCarson next challenges the admissibility at trial of four prior convictions — two for possession of a gun and two for distribution of crack cocaine — on the ground that the evidence was inadmissible under Rules 404(b) and 403 of the Federal Rules of Evidence. Rule 404(b), which governs the admissibility of “[ejvidence of other crimes, wrongs, or acts,” excludes evidence submitted “to prove the character of a person in order to show action in conformity therewith,” whereas Rule 403 provides that otherwise relevant evidence, including evidence of other crimes, “may be excluded if its probative value is substantially outweighed by the danger of unfair prejudice”; the application of both Rules is committed to the discretion of the district court.
United States v. Bowie,
First, it is clear the evidence is admissible under Rule 404(b). In
United States v. Cassell,
McCarson nonetheless argues the evidence of his prior convictions for possessing firearms and selling crack cocaine is inadmissible under Rule 404(b) because his knowledge and intent were not at issue; the only issue was whether he possessed the gun and the drugs. In
Cassell,
however, we rejected the distinction between knowledge and possession when a defendant is charged with constructive possession, because “[a] successful conviction” for constructive possession requires proof of “a mental element (knowing possession),” as well as “a physical element (dominion and control ...).”
Finally McCarson contends the evidence of his prior convictions, even if relevant, should have been deemed inadmissible under Rule 403. It is clear, however,
*174
the district court did not “grave[ly] abuse” its discretion in admitting McCarson’s prior convictions.

III. Conclusion
For the reasons given above, the judgment of the district court is
Affirmed.
Notes
McCarson challenges neither the reasonableness of the Marshals' belief McCarson was at his girlfriend's apartment nor their authority, in connection with effecting the arrest, to enter the bedroom where they found the contraband. Although counsel contended at oral argument that the evidence was not found in plain sight, that argument appears nowhere in the defendant’s briefs and so is not properly before us.

We have said as much in analogous cases on at least two occasions,
