House votes to overturn border wall emergency declaration

The House on Tuesday rebuked President Donald Trump over one of his signature issues, passing a resolution to overturn his emergency declaration to unlock money for wall construction at the US southern border.

The vote was 245-182. Thirteen Republicans voted with Democrats to pass the measure.

The resolution will next be taken up by the Senate, where it will put Republican unity to the test, though Senate leaders have signaled they will not bring it to a vote immediately.

It is not yet clear how many Republicans will vote for the resolution in the Senate, but it looks likely to pass the upper chamber, despite the fact that Republicans hold a majority. That would be yet another blow to the President, who has said he will veto the resolution if it comes to his desk.

A test of Republican unity in the Senate

If four Republicans join all the Democrats in the Senate to pass the resolution, the measure would then face a presidential veto. The White House formally issued a veto threat on Tuesday afternoon.

Congress would then need an overwhelming majority — two-thirds of its members — in both chambers to overrule the President. It is unlikely that there would be enough support on Capitol Hill to overturn a veto.

So far, there are three Republicans who have signaled they will vote in favor of the resolution. And Senate GOP aides fully expect the resolution to pass when it is brought to the floor.
