President Donald Trump has one thing to say after the Republican-led Senate voted to block his national emergency declaration for border wall funding: “VETO!”

Trump tweeted the one-word response Thursday after the Senate voted 59-41 in favor of a resolution to block the measure. A total of 12 Republicans voted with Democrats to rebuke the president.

Later, the president explained: “I look forward to VETOING the just passed Democrat inspired Resolution which would OPEN BORDERS while increasing Crime, Drugs, and Trafficking in our Country. I thank all of the Strong Republicans who voted to support Border Security and our desperately needed WALL!”

In a stunning rebuke, the Republican-controlled Senate has voted to terminate President Donald Trump’s declaration of a national emergency at the U.S.-Mexico border.

The Senate voted 59-41 for a resolution to halt Trump’s emergency order. Trump has promised to veto it, and it is unlikely that Congress will have the votes to override him.

It’s the first time Congress has used its power to reject a presidential emergency order.

Trump wants to use his declaration to steer $3.6 billion more to border barriers than lawmakers approved. He had warned Republicans to stick with him on the vote. He said doing otherwise would be siding with Democratic House Speaker Nancy Pelosi. But several Republicans defied that warning.

The Senate is poised to reject President Donald Trump’s declaration of a national emergency to build a wall along the U.S.-Mexico border, with several Republicans joining Democrats in opposing Trump’s use of executive power.

Enough senators have voted “yes” to pass a resolution Thursday terminating Trump’s emergency order. The vote is still ongoing.

The resolution has already cleared the House, so it will soon head to Trump’s desk. He has promised to reject it by issuing what will likely be his first veto. It is unlikely that Congress will have the votes to override him.

Thursday’s vote would be the first time Congress has rejected a presidential emergency under the 1976 National Emergency Act.

Republican Sens. Mitt Romney and Sen. Lamar Alexander have endorsed a resolution passed by the Democratic-controlled House to block President Donald Trump from using emergency powers to fund his long-promised U.S.-Mexico border wall.

That brings to seven the number of Republicans who have announced they will cross Trump on a vote expected for Thursday afternoon, ensuring the measure will pass.

Romney was the GOP’s 2012 presidential nominee and a sometimes critic of Trump; Alexander is among the senior guardians of the Senate as an institution. Lawmakers oppose Trump’s action because they see the power of the purse as Congress’ prerogative.

Romney said that “this is a vote for the Constitution and for the balance of powers that is at its core.”

Trump has promised to veto the measure and is sure to be sustained by his House GOP allies.
