Iran live updates: Trump calls GOP backers of war powers resolution 'grandstanders'

President Donald Trump on Thursday called the House-approved war powers resolution a "meaningless vote," and the four Republicans who crossed party lines to advance the legislation "grandstanders" -- saying their actions were "unpatriotic."

"Yesterday, in a meaningless vote, the House voted, 4 bad Republicans and all of the Dumocrats, to limit my War Powers, right in the middle of my final negotiations to end the War with the Islamic Republic of Iran. Who would do such an unpatriotic thing," Trump wrote Thursday morning in a post to his social media platform.

Trump claimed that the four Republicans know where negotiations stand between the U.S. and Iran and "should be ashamed of themselves."

Israel and Lebanon have reached an agreement on the implementation of a ceasefire, according to two sources familiar with the negotiations.

This comes after hours of negotiations in Washington on Wednesday.

President Donald Trump indicated on Wednesday that the U.S.-Iranian ceasefire remains intact despite another exchange of fire between the two countries' militaries overnight.

The exchange saw an Iranian strike on Kuwait's international airport that killed at least one person and wounded at least 60 others, Kuwait's Ministry of Foreign Affairs said.

Trump acknowledged the exchange of fire in remarks with reporters on Wednesday and said ceasefires are defined differently there.

"I'd say that part of the world, ceasefire is when you're shooting in a more moderate manner," he said. "A ceasefire there is much different than a ceasefire in other parts of the world."

He also seemed optimistic that Iran was "pretty close" to signing a deal, claiming it could happen over the weekend.

"I hear the negotiation itself is going very well, actually. Very well," he said. "I mean if it happens -- I mean it might not happen, you know, who knows? -- but if it happens, it could happen, like, over the weekend."

The House adopted a resolution to rein in President Donald Trump's Iran war powers for the first time since the start of the conflict, by a vote of 215-208 on Wednesday.

GOP Reps. Thomas Massie, Brian Fitzpatrick, Tom Barrett and Warren Davidson voted in favor with all Democrats.

Though this is a rebuke of the president's handling of the war with Iran, the resolution is symbolic in nature while expressing the sentiment of the House.

The resolution, which sends a strong message to the administration, heads to the Senate for consideration. It is not required to go to the president's desk since it is a concurrent resolution.
