Rep. John Kline is the only member of Minnesota’s Congressional delegation to vote against an amendment on Thursday that requires federal contractors working with the Department of Housing and Urban Development to comply with LGBT non-discrimination policies.

The amendment was introduced by Rep. Scott Peters, a Democrat from California, and it prohibits federal contractors working with HUD from discriminating based on race, color, religion, sex, sexual orientation, gender identity or national origin.

“No American should be fired or denied a job or place to live for being who they are or because of who they love,” Peters said in a statement. “My amendment would demonstrate that Congress is willing to lead on equality and fairness as we work toward full non-discrimination provisions for LGBT individuals.”

Minnesota Republican Reps. Erik Paulsen and Tom Emmer voted for the amendment as did Democratic Reps. Collin Peterson, Rick Nolan, Tim Walz, Keith Ellison, and Betty McCollum.

The Minnesota DFL immediately went on the attack, criticizing Kline for his vote.

“Congressman Kline stood alone among the Minnesota delegation to say that he doesn’t think it’s a problem for someone to be fired or denied a promotion because they are gay, lesbian, bisexual, or transgender, and that’s going to be a huge problem when he asks to be re-hired by the voters again in 2016,” DFL Chairman Ken Martin, said in a statement.
