President Trump to deliver remarks in Oval Office

House Speaker Nancy Pelosi said in a statement that the chamber will vote March 26, after Congress returns from recess, to vote on overriding Trump's veto.

"I'd like to thank all of the Great Republican Senators who bravely voted for Strong Border Security and the WALL", Trump tweeted ahead of his veto action.

But the Senate margin fell short of the 67 votes needed for a veto override. Attorney General William Barr is also at the President's veto event. "Watch, when you get back to your State, they will LOVE you more than ever before!"

Still, a White House official said Trump won't forget when senators who opposed him want him to attend fundraisers or provide other help.

The resolution passed the GOP-controlled Senate by a vote of 59-41 - with 12 Republicans defying the president - after it was approved by the Democrat-controlled House.

The declaration of an emergency allowed the administration to access over $6bn in additional funds not appropriated by Congress to build the wall.

"The world continues to be a risky place and we'll continue in the war against terrorism", said the senator.

"House Republicans will have to choose between their partisan hypocrisy and their sacred oath to support and defend the Constitution", she added.

On 15 February Trump invoked the National Emergencies Act of 1976, claiming there was a crisis on the border that required the construction of walls to protect the United States.

Recent months have seen a surge in unauthorized crossings of the USA border with Mexico.

"People hate the word invasion, but that's what it is". Democrats deny there is an emergency at the border, saying border crossings are at a four-decade low.

The border wall project still faces a variety of legal challenges, and despite Trump's veto, House and Senate votes against the emergency declaration could carry some weight in the courts. He explained the legality of Donald Trump's countermeasure.

"I think the basic premise of Mike [Lee's] bill is correct", Republican Senator Jerry Moran said Thursday.

Trump's national emergency declaration almost a month ago is paired with a number of executive actions created to make approximately $8 billion of funding available to begin construction on a wall along the southern border.
