US Senate

Twelve Republican senators broke party ranks to side with Democrats, approving a proposal to revoke the proclamation by 59-41.

The Democratic-controlled House of Representatives last month backed the measure.

Following Thursday's vote, Mr Trump tweeted: "VETO!"

Congress needs a two-thirds majority of both chambers to override a presidential veto, which is viewed as unlikely in this case.

Nevertheless, the vote will be seen as an embarrassing loss for the president on his signature domestic issue.

The House of Representatives earlier approved the bill comfortably. Republicans have majorities in both houses of Congress.

For final approval the legislation must go back to the House on Wednesday for a procedural issue.

If it passes, as expected, it will be President Donald Trump's first major legislative triumph.

Critics say the package is a deficit-bloating giveaway to the super-rich.

But Republicans argue the tax cuts for corporations, small businesses and individuals will boost economic growth.
