U.S. Rep. Dave Loebsack, D-Iowa, is "leaning against" voting for authorizing a military strike against Syria, an aide said Thursday.
Loebsack, who expressed considerable skepticism about a strike on Monday, will continue to receive briefings from the Obama administration and hear from his constituents, spokesman Joe Hand said.
"But at this point, he does not believe the president has yet made his case, so he is leaning against authorization," he said.
Loebsack is a member of the House Armed Services Committee, and on Monday, he expressed concerns about what would happen in the aftermath of a missile strike. He'll take part in an Armed Services hearing on the matter next Wednesday.
Rep. Cheri Bustos, D-Ill., still has not decided how she would vote and is not leaning one way or the other, according to her office. Bustos said Monday she has a series of questions to ask.
On Wednesday, the Senate Foreign Relations Committee voted, 10-7, to approve a resolution authorizing the strike.
U.S. Sen. Dick Durbin, D-Ill., a member of the committee, supported the measure and told reporters in Thomson after a town hall meeting that it is necessary.
"What we want to do is stop this madman from using chemical weapons on his own people," he said.
The Obama administration already has said the regime is responsible for an Aug. 21 attack that killed more than 1,400 people. It says a strike would degrade and deter his chemical weapons capacity.
Still, the measure approved Tuesday also includes a provision co-sponsored by Sen. John McCain, R-Ariz., that says the policy of the United States is to "change the momentum" in the civil war in Syria.
The idea, Durbin said, is to help Syrian opposition that has been "vetted"
He rejected the idea there is a chance American troops could be sent to Syria.
"The resolution that we passed yesterday made it clear that will not happen," he said.
Durbin said he understood polls that say more Americans are against a strike than for it. He blamed the run up to the war in Iraq and the length of the war in Afghanistan.
"They were lied to about Iraq. We were told there were weapons of mass destruction, therefore we had to invade. It wasn't true," Durbin said. He added that the war in Afghanistan has turned into the longest in U.S. history.
"The American people have a right to be skeptical," he said.
But he said the resolution is limited in duration and scope and prevents the use of combat troops.
Durbin voted to support the war in Afghanistan but opposed the Iraq War.
