Donald Trump threatened to close the whole U.S.-Mexico border on Friday morning in a bid to force congressional Democrats’ hands as the partial government shutdown nears its second week.

In a Friday morning Tweetstorm, Trump not only threatened to close the border unless he got funding but also warned of a new caravan of migrants heading north to the Southern U.S. border. “Word is that a new Caravan is forming in Honduras and they are doing nothing about it,” Trump tweeted, without any sourcing of where he is getting this “word.”

Trump tweeted:

We will be forced to close the Southern Border entirely if the Obstructionist Democrats do not give us the money to finish the Wall & also change the ridiculous immigration laws that our Country is saddled with. Hard to believe there was a Congress & President who would approve!

….The United States looses soooo much money on Trade with Mexico under NAFTA, over 75 Billion Dollars a year (not including Drug Money which would be many times that amount), that I would consider closing the Southern Border a “profit making operation.” We build a Wall or…..

…..close the Southern Border. Bring our car industry back into the United States where it belongs. Go back to pre-NAFTA, before so many of our companies and jobs were so foolishly sent to Mexico. Either we build (finish) the Wall or we close the Border……

…..Honduras, Guatemala and El Salvador are doing nothing for the United States but taking our money. Word is that a new Caravan is forming in Honduras and they are doing nothing about it. We will be cutting off all aid to these 3 countries – taking advantage of U.S. for years!

Trump’s Twitter threat comes amid hardening positions on both sides as the partial government shutdown, affecting about 800,000 federal employees and many more federal contractors, shows no signs of abating. Congressional Democrats refuse to give the Trump administration the $5 billion its demanding for a border wall, signaling they’re only willing to appropriate a bit over $1 billion for “border security” measures — specifically excluding a wall.

The standoff began early in the morning of Dec. 22 when a swath of federal agencies ran out of funding for the fiscal year. House Democrats will gain some leverage in the fight once they assume the House majority on Jan. 3. But even if the House and Republican-controlled Senate passed a “clean” budget funding extension that included no wall funding, Trump would likely veto it.

Trump has previously threatened to close the entirety of the U.S.-Mexico border. The president’s threat to shut down the 2,000-mile-long southern border would disrupt hundreds of billions of dollars a year in trade and an average of $821 million each day.

Twitter had some thoughts:

Go ask @mexico for the $ like you promised hundreds of times during the campaign! This is the biggest campaign promise broken by a President since George H. W. Bush's "read my new lips" about no next taxes and then he raised taxes. Bush lost re-election. So will Trump…badly

Republicans have been in charge of all three branches of government since your inauguration. It is not Democrats' fault if you don't have your "wall." I seem to remember your *promise* that Mexico would pay for it…they aren't. You turned down bipartisan deals… It is on you.

How many times do people have to explain it to you, there is already a wall. You just want a new one. The state on the border and the border patrol all say we don't need a new wall. But more cameras other detection equipment, and other resources.

I see you’ve chosen the “be carried out in a straitjacket” approach. Also, you’re the obstruction. Everyone knows it. Resign. #ResignTrump
