Frustrated by the large number of Central Americans who have been entering the country from Mexico, President Trump doubled down on his threat to close the Southern U.S. border.

President Trump used his veto pen for the first time Friday, after Congress tried to reverse his national emergency declaration and rein in spending on a wall along the U.S.-Mexico border.

Congressional critics do not appear to have the votes to override Trump's veto. So, as a practical matter, the administration can continue to spend billions of dollars more on border barriers than lawmakers authorized, unless and until the courts intervene.

President Trump abruptly halted spending talks at the White House on Wednesday, after congressional Democrats again rejected his demand for a $5.7 billion border wall.

On Twitter, Trump dismissed the negotiations as a "total waste of time," as a partial government shutdown stretched into its 19th day. He added, "I said bye-bye, nothing else works!"

President Trump used his first prime-time address from the Oval Office to make the case for his controversial border wall. The president's demand for $5.7 billion in wall funding — and Democrats' opposition — has led to a partial shutdown of the federal government.

Here we check some of the arguments made by the president and top Democrats in their response.

Trump's Speech

Claim 1: Humanitarian and security crisis

"There is a growing humanitarian and security crisis at our Southern border."

The White House is planning a media blitz as President Trump pushes for a wall along the Southern border, which congressional Democrats have repeatedly rebuffed. This week's events involving the president come as a partial shutdown of the federal government drags into its third week with no apparent end in sight to the impasse.

President Trump on Friday issued an executive order freezing the salary rates for federal workers. The order wasn't a surprise but for some 800,000 federal employees furloughed during the partial government shutdown or working without pay, it was like rubbing salt into a wound.

Trump did not announce who would replace Kelly but said that would come in a day or two.

After a brief pause to pay respects to victims of the Pittsburgh synagogue shooting, Trump hosted a political rally in Fort Myers, Fla., on Wednesday. It's one of 11 campaign rallies the president will hold in the next six days, in a furious final sprint to next week's midterm elections.

President Trump will visit Pittsburgh on Tuesday to show support for victims of the city's deadly synagogue shooting.

A White House spokeswoman dismissed suggestions that Trump's rhetoric has contributed to a hostile climate in the country. She said Trump won't shy away from drawing distinctions with Democrats in the final week before the midterm elections.

White House counsel Don McGahn has left the job effective Wednesday. But his influence will live on for years, thanks to the dozens of conservative judges that McGahn helped President Trump put on the federal bench.

The grueling confirmation of Supreme Court Justice Brett Kavanaugh marked an explosive end to McGahn's White House tenure. But he's also worked more quietly in the last two years to put his stamp on the lower courts.

USA Today published an opinion column by President Trump Wednesday in which the president falsely accused Democrats of trying to "eviscerate" Medicare, while defending his own record of protecting health care coverage for seniors and others.

The column — published just weeks ahead of the midterm elections — underscores the political power of health care to energize voters. But it makes a number of unsubstantiated claims.

The president boasted that he's accomplished more during his time in office than almost any previous administration — a claim that drew immediate laughter from the assembled diplomats and other world leaders.

Trump pressed ahead, undaunted.

Confirmation hearings for Supreme Court nominee Judge Brett Kavanaugh opened on a contentious note Tuesday, with Senate Democrats raising noisy objections that much of Kavanaugh's lengthy paper trail is still off limits.

The president's equivocation drew bipartisan condemnation, capping a week in which Trump alienated allies and cozied up to adversaries.

Trump himself declared his meeting with Russian President Vladimir Putin on Monday in Helsinki a success, in what he called the "proud tradition of bold American diplomacy."
