Maine Democratic Congressman Jared Golden joined Republicans in defeating a measure to limit the president’s ability to wage war in Iran.

Golden was the only House Democrat to vote against the resolution on Thursday, which failed by a single vote, 213-214.

The resolution was aimed at forcing the Trump administration to withdraw forces from the conflict unless Congress authorizes further military action.

Golden said Thursday his vote comes amid a ceasefire in the conflict, saying the resolution would “weaken our hand” in ongoing negotiations to prevent Iran from building nuclear weapons.

It comes a day after Maine Republican Sen. Susan Collins voted with her party to block a similar effort in the Senate.

Sen. Collins has said she supports the current level of involvement in the conflict, but sending ground troops overseas would require approval for Congress.
