President Trump on Wednesday called on Congress to take immediate action to strengthen border laws while accusing Democrats of standing in the way of legislation.

In a morning tweet, the president said that current border laws are "very weak" and noting that "strong action" would be taken Wednesday.

This comes a day after the president said that he wants to deploy U.S. troops to guard the southern border with Mexico until his proposed border wall is completed.

“Until we can have a wall and proper security, we are going to be guarding our border with the military,” Trump said Tuesday during a meeting with Baltic state leaders.

Trump has received increased pressure from his base to score a policy win on immigration after lawmakers did not address his plea for $25 billion in wall money in recent spending legislation.

The president instead got just $1.6 billion for border fortifications in a recent government funding bill, and most of that money cannot be used to build new portions of the wall.

Trump on Tuesday also cited a “caravan” of Central American migrants heading for the U.S. border, later saying he heard reports the caravan was broken up, crediting his threat to pull out of the North American Free Trade Agreement (NAFTA) if Mexico does not arrest more migrants.

“They did it because, frankly, I said you really have to do it,” the president said. “We're going to have a relationship on NAFTA; we're going to have to include security in NAFTA.”

The president has been attempting to renegotiate NAFTA terms with Mexico and Canada for months. He exempted the countries from his recent steel and aluminum tariffs and reportedly hopes to have an updated version of NAFTA to unveil during the Summit of the Americas later this month.
