Democrats splintered over a resolution seeking to block the U.S. from assisting Israel's war against Hezbollah, an Iranian-backed terrorist group, on Thursday. 

The measure, offered by progressive Rep. Rashida Tlaib, D-Mich., would require President Donald Trump to withdraw U.S. forces from Lebanon. For months, Israel and Hezbollah, a U.S.-designated terrorist group and Iranian proxy, have been at war in southern Lebanon, but the United States has not joined the conflict.

A bipartisan coalition of lawmakers, including House Minority Leader Hakeem Jeffries, D-N.Y., rejected the measure. Critics argued the resolution could aid Hezbollah and potentially hamstring U.S. military operations in the country. 

Tlaib's resolution failed 92-324, with more than half of House Democrats joining nearly all Republicans to vote it down.

Rep. Thomas Massie, R-Ky., an Israel critic, was the lone Republican to support Tlaib's measure. Meanwhile, Reps. Derek Tran, D-Calif., and Betty McCollum, D-Minn., voted present.

House Democratic leaders said shortly before the vote they would oppose Tlaib's resolution and work with the progressive lawmaker on a narrower measure exempting some U.S. military operations in the country. Their statement also denounced Hezbollah as a "violent terrorist organization" and a "sworn enemy of the United States."

Tlaib, who has accused Israel of committing "ethnic cleansing" in Lebanon, did not mention Hezbollah in her resolution. She and other proponents of the measure also avoided discussing the Iranian proxy force during heated floor debate over the measure. 

Republicans highlighted the omission and accused the legislation’s supporters of serving as "proxies for Hezbollah."

"Apparently they don't want to see Israel killing Hezbollah, even though it's Hezbollah that is killing Israeli children, Israeli adults, Israeli elders," House Foreign Affairs Committee Chairman Brian Mast, R-Fla., said Wednesday, referring to his Democratic colleagues.

Tlaib asserted that her resolution would only affect U.S. forces actively engaged in hostilities. Republicans, however, disputed that claim and suggested it would hurt U.S. efforts to counter Hezbollah. 

"It doesn't say anything about [whether] you can keep the Marines that are in the embassy," Mast said, referring to the U.S. embassy in Beirut. "That's a pretty big oversight. It doesn't say anything about whether we can keep United States armed forces that are training missions with the LAF [Lebanese Armed Forces]. Again, pretty big oversight."

The debate turned personal when Rep. Max Miller, R-Ohio, a member of the House Foreign Affairs Committee, linked Tlaib to Hezbollah.

"Hezbollah is a terrorist organization ... and its members are butchers that you like to hang out with to a certain extent," the Ohio lawmaker said, referring to Tlaib.

A shouting match between the two then broke out, with Tlaib demanding that Miller’s remarks be stricken from the record.

The presiding chair ultimately complied with her request, but Miller doubled down on his remarks.

"Yes, I said it. I own it, and I stand by it," Mast said on behalf of Miller on the floor.

Tlaib’s failed war powers resolution comes as Iran has sought to tie Israel’s invasion of Lebanon to its ceasefire negotiations with the United States.

Hezbollah, which has long helped Iran project power in the region, rejected a ceasefire agreement between Israel and Lebanon’s government Thursday.
