President Donald Trump claimed once again that he would close the entire U.S. southern border in response to an advancing caravan of Central Americans, in a Monday morning tweet.

“We would save Billions of Dollars if the Democrats would give us the votes to build the Wall,” Trump tweeted. “Either way, people will NOT be allowed into our Country illegally! We will close the entire Southern Border if necessary. Also, STOP THE DRUGS!”

Trump’s tweet comes during an impending fight with Congress over a spending bill, in which he is demanding 5 billion dollars in funding for his proposed wall along the U.S. southern border. Democratic lawmakers conversely have said they will only provide Trump with 1.6 billion dollars, setting the stage for a possible government shutdown.

The fight was slated to come to a head this weekend as the deadline for spending approached but Trump said he would allow for a temporary 2 week spending bill in order to let the nation mourn the passage of former President George H.W. Bush.

“If they come — which they have — to talk about an extension because of President Bush’s passing, I would absolutely consider it and probably give it,” he told reporters Sunday.

Trump has remained defiant in his request for $5 billion, saying to Politico, “I am firm. We need border security, of which a wall is part of it. But we need border security. All you have to do is look at the borders.”

“We need border security in this country, and if that means a shutdown I would totally be willing to shut it down,” he continued. “And I think it’s a really bad issue for the Democrats.”

The president elaborated that he believes any potential government shutdown over border wall funding would be politically beneficial to him saying, “I will tell you politically speaking, that issue is a total winner. People look at the border, they look at the rush to the police, they look at the rock throwers and really hurting three people, three very brave Border Patrol folks — I think that it’s a tremendous issue.”
