Homeland Security Secretary Markwayne Mullin has reportedly shared a Washington, D.C., home with Rep. Jason Smith for three years, renewing speculation about the two men.Mullin, a former professional fighter, met Smith, the Missouri Republican who chairs the House Ways and Means Committee, while leading bipartisan congressional workouts, The New York Times reported in 2014. The workouts also included former Rep. Aaron Schock, an Illinois Republican who came out as gay after leaving Congress.Mullin has called Smith his best friend in Congress. Sources close to Mullin told the Daily Mail last week that he has lived with Smith in a row house near Capitol Hill for the past three years. Lawmakers sometimes share housing in Washington, and Mullin represented Oklahoma in the Senate for much of that period. The arrangement reportedly continued after his confirmation as Homeland Security secretary.“It's strange that a cabinet secretary still has a roommate," one source told the Mail. “Maybe it's because he is so rarely in DC since he flies home so often. He literally uses it as a crash pad.”Related: Senate confirms brawler Markwayne Mullin to lead Homeland Security Department after Kristi Noem See on Instagram Mullin’s financial disclosure lists a separate Washington residential property held through Mullin Realty LLC and valued at $1 million to $5 million.
