ANNAPOLIS, Md. — Kristin Beck, a transgender former Navy SEAL, is challenging Maryland’s longest-serving U.S. representative, Democrat Steny Hoyer, in the 2016 primary.

Beck filed the paperwork Monday with the state Board of Elections, listing a campaign address in Rockville. She didn’t immediately respond Thursday to an emailed interview request from The Associated Press. A telephone number listed on the board’s website and Beck’s campaign website wasn’t set up.

Beck, 48, born Christopher Beck, gained fame after she came out publicly in a CNN interview in 2013, two years after retiring from a 20-year military career. She calls herself a “liberal conservative” on her Facebook page, advocating campaign spending limits and term limits for all elected offices.

Beck’s campaign website highlights her military service and criticizes the government’s handling of the home-loan crisis. It says Hoyer “has been too busy helping Wall Street since 2008 to even notice Main Street.”

Hoyer, 75, said in a statement he is proud to represent the 5th Congressional District, a southern Maryland seat he first won in a 1981 special election.

“I appreciate the support of my constituents and will continue to work on their behalf to address their priorities, and earn their vote in 2016,” Hoyer said.

Beck considered running last year in Florida for a House seat left vacant by the death of Republican Bill Young but apparently didn’t file.

Hoyer is the Democratic whip, the No. 2 position among House Democrats.

No other candidates have filed for the primary.
