The House of Representatives is set to vote on an Iran war powers resolution at 11:30 a.m. on Thursday.

The resolution would call on President Donald Trump to terminate the use of U.S. armed forces in hostilities against Iran or any part of the Iranian military or government unless a declaration of war or authorization to use force is enacted.

Previously, this effort has narrowly failed in the House. However, as the war continues and lawmakers face mounting questions about Trump’s actions, additional Republicans could choose to support the effort.

Given the slim margins in the House, this vote could be close. On Wednesday, the Senate failed to advance a similar Iran war powers resolution.

As he warned the Iranian regime to reach a deal with the U.S., Defense Secretary Pete Hegseth emphasized how degraded its capabilities are.

"While you are digging out, which is exactly what you're doing digging out of bombed out and devastated facilities. We are only getting stronger," Hegseth said.

"You are digging out your remaining launchers and missiles with no ability to replace them. You have no defense industry, no ability to replenish your offensive or defensive capabilities," Hegseth said.

Asked about reporting that there is U.S. intelligence indicating that China is preparing weapons shipments to Iran during the ceasefire, Defense Secretary said China has assured the U.S. this is not the case.

"President Trump has a very strong and direct relationship with President Xi, and they've communicated on that, and China has assured us that that indeed is not going to happen," Hegseth said.

Trump and Xi are expected to meet in China in May, a trip that was delayed after the start of the U.S.-Israeli war with Iran.

Despite Iranian leadership's command and control capabilities being "highly degraded," Iran has a "high incentive" to maintain in the ceasefire, Defense Secretary Pete Hegseth said in a press conference at the Pentagon Thursday.

Chairman of the Joint Chiefs of Staff Gen. Dan Caine warned that during the ceasefire "the United States Joint Force remains postured and ready to resume major combat operations at literally a moment's notice."

Chinese Foreign Minister Wang Yi voiced support for Iran and called for "maintaining the momentum of the ceasefire and negotiations."

Wang spoke on Wednesday with Iranian Foreign Minister Abbas Araghchi, according to a readout posted by the Chinese ministry.

"Wang Yi stated that China, as always, supports Iran in safeguarding its sovereignty, security, and national dignity," the readout said.

Wang's office said the minister also told Araghchi that "freedom of navigation and safety in the international strait should be guaranteed, and efforts to restore normal navigation in the strait are the unanimous call of the international community."

The U.S. this week began a blockade of the strait. "U.S. service members continue to monitor and patrol regional waters in support of the U.S. blockade on ships entering or exiting Iranian ports," U.S. Central Command said early on Thursday.
