A day after his Thanksgiving threat to shut the entire border with Mexico if the migrants storm it, President Trump on Friday called for a bipartisan “security package” from Congress that includes funding for his long-promised wall.

“Republicans and Democrats MUST come together, finally, with a major Border Security package, which will include funding for the Wall,” the president said in a tweet.

“After 40 years of talk, it is finally time for action. Fix the Border, for once and for all, NOW!” he added from his Mar-a-Lago resort in Florida.

The Black Friday broadside followed his comments Thursday, when he threatened a partial government shutdown over lawmakers’ refusal to allocate billions of dollars for the wall.

“Could there be a shutdown? There certainly could, and it will be about border security, of which the wall is a part,” Trump told reporters during the holiday.

Pointing to the caravans of Central American migrants making their way toward the US, Trump said he had the authority by executive order to close the border “for a period of time until we get it under control.”

Trump claimed he’d already used his authority to seal off the southern border.

“Two days ago, we closed the border. We actually just closed it, said nobody’s coming in because it was just out of control,” he said.

Actually, officials only shut down one port of entry – San Ysidro in California – for several hours Monday to ramp up security due to concerns about a possible influx of asylum-seekers.

Authorities closed northbound lanes into the US and reopened most of them a short time later.

The president also said Thursday that the 5,900 troops he ordered deployed to the border could use lethal force to block the migrants from entering the US.

“If they have to, they’re gonna use lethal force,” he said. “I’ve — I’ve given the OK. If they have to. I hope they don’t have to.”

In a statement Thursday, Secretary of State Mike Pompeo supported the president’s warning.

“The caravans will not be permitted to enter the United States. There are real dangers to the safety and human rights of migrants from those who would prey on them,” he said.

Legal experts have warned that the use of lethal force may violate the Posse Comitatus Act, which forbids the military from being used for civilian law enforcement.

Congress has until Dec. 7 to fund the rest of the government after lawmakers failed to approve seven of 12 funding bills.

Before the midterm elections, in which the GOP lost control of the House, Trump warned voters about the “invasion” by the caravans, which he claimed included criminals, MS-13 gang members and Middle Easterners.

His critics called the deployment of thousands of troops a political stunt.
