Fox Business Network's Dagen McDowell asked on "Outnumbered" Wednesday whether it's true that Mexico is indirectly funding a wall along the southern border, as President Trump claimed on Twitter hours before.

In a tweet Wednesday morning, Trump said "Mexico is paying for the Wall" through a new trade deal and that "Much of the Wall has already been fully renovated or built."

Mexico is paying for the Wall through the new USMCA Trade Deal. Much of the Wall has already been fully renovated or built. We have done a lot of work. $5.6 Billion Dollars that House has approved is very little in comparison to the benefits of National Security. Quick payback! — Donald J. Trump (@realDonaldTrump) January 2, 2019

Responding on "Outnumbered," McDowell asked why Trump demanded $5 billion for additional border security measures, including the long-promised wall, triggering a partial government shutdown in late December.

"Why in the name of Santa Claus, the Easter Bunny and the Tooth Fairy are you talking about Mexico is paying for it? Then why did you shut the government down? In terms of the political messaging, this makes zero sense to me," she argued.

She said Trump may view the negotiations in the same way that President George H.W. Bush looked at his promise not to raise taxes. The 41st president eventually did sign off on tax increases in a deal with Democrats.

McDowell said Democrats and Republicans should be able to negotiate an agreement - favored by Sen. Lindsey Graham (R-S.C.) - to approve the funds Trump wants, but also grant work permits to Dreamers.

"Wouldn't it benefit the Democrats if they can get on board with that?" she asked.

Democrat Richard Fowler responded that Trump has been unwilling to compromise so far with Nancy Pelosi and Chuck Schumer. Lisa Boothe said she sees "no middle" opening up right now to allow for a bipartisan agreement to reopen the government.

"This is gonna go on until people start feeling more pain and they start putting pressure on Congress," said Boothe.
