Donald Trump said he will not accept a deal to avert another government shutdown without money for his long-desired border wall, pushing back on Democrats who stressed their opposition to a wall…and even claimed that Speaker Nancy Pelosi would eventually beg him for the wall.

“If they’re not going to give money for the wall…it’s not going to work,” Trump told reporters in the Oval Office on Thursday.

Trump said he would wait to see if Congress can come up with an agreement before the Feb. 15 funding deadline before he decides whether to declare a national emergency in a bid to build the wall on his own.

Citing what he said is a threat posed by a new migrant caravan making its way toward the U.S., Trump claimed that “Nancy Pelosi will be begging for a wall.”

Trump’s comments come after Pelosi said earlier Thursday that Democrats remain adamantly opposed to wall funding, but could provide money for new fencing and other barriers in a spending bill.

“There’s not going to be any wall money in the legislation,” Pelosi said during her weekly press briefing in the Capitol. “However, if they have some suggestions about certain localities where technology, some infrastructure is appropriate, … that’s part of the negotiation.”

Trump has cast doubt on bipartisan spending talks, arguing earlier in the day that Republicans were “wasting their time” by engaging with Democrats who oppose wall funding.

While Trump has previously said he would be open to calling structures along the border “steel slats” or a “barrier,” he said Thursday he would return to demanding a wall.

“Lets just call them WALLS from now on and stop playing political games! A WALL is a WALL!” Trump tweeted.

WATCH:

TRUMP is incoherent, claims "we're building the wall right now" but also says of potential border security deal, "if there's no wall it doesn't work."
