On Thursday the Senate will attempt to override Trump’s veto of the resolution that places some constraints on his power to take military action against Iran without congressional signoff.

Majority Leader Mitch McConnell of Kentucky announced on Wednesday that the chamber shall hold a vote to override the veto at 1:30 p.m. It is expected to be short of almost the two-thirds the support needed, essentially ending the attempt to overturn Trump’s veto.

The vote will come almost a day after Trump vetoed the resolution and slammed Congress for its passage, saying they “should not have passed this resolution.”

“This was a very insulting resolution, introduced by Democrats as part of a strategy to win an election on November 3 by dividing the Republican Party. The few Republicans who voted for it played right into their hands,” he said in a statement.

The resolution was spearheaded by Senator Tim Kaine, and would require Trump to pull any U.S. troops from any hostilities against Iran within the time period 30 days unless he gets congressional approval for the military action.

“I urge my colleagues to join me in voting to override his veto. Unless there’s a carefully reached consensus in Congress that war is necessary, we should not be sending our troops into harm’s way,” Kaine said to the press in a statement on Wednesday.

The resolution passed initially the Senate in a 55-45 vote, in February with eight Republican senators supporting it. After that it passed the House in a 227-186 vote held in March it was one of the last votes to be held before lawmakers left town amid the coronavirus pandemic.

Democrats pledged to force a vote on the resolution, which they are entitled to do under the War Powers Act, after the United States launched an airstrike that killed Iranian Gen. Qassem Soleimani, sparking uncertainty and days of escalating tensions between Washington and Tehran.
