Earlier in the day, President Trump defended his decision to use a drone strike to take out General Qassem Soleimani, the head of Iran's Quds force, blamed for attacks on U.S. troops in the Middle East.
"We caught a total monster, and we took him out," Mr. Trump said at an infrastructure event at the White House. "And that should have happened a long time ago. We did it because they were looking to blow up our embassy."
Amid complaints that the Trump Administration had not shown evidence of an 'imminent' threat from Soleimani, the President said the killing of an American contractor the week before was one clear reason to act.
"We had a shot at him, and I took it, and that shot was pinpoint accurate. And that was the end of a monster," Mr. Trump said.
At a campaign rally Thursday evening in Toledo, the President also made clear he felt the decision was the right one.
While the Senate is expected to vote on a War Powers Resolution dealing with Iran, it is a different form, making it unlikely that the House and Senate will agree on any plan - turning this House vote into more of a public rebuke.
"Our concerns were not addressed by the President's insufficient War Powers Authorization, which was classified in its entirety, leaving the Congress and the public in the dark about our national security," said House Speaker Nancy Pelosi.
"Congress is reasserting our long-established oversight responsibilities as we mandate that, if no further Congressional action is taken, the Administration's military hostilities with regard to Iran must end," the Speaker added.
