NBC News national political reporter Heidi Przybyla explained that President Donald Trump's signing of the omnibus budget bill despite his veto threats was a tantrum resulting from Congress joining Mexico in refusing to pay for his border wall.

MSNBC's Katy Tur read a quote Peter Alexander relayed from a senior Democratic Party aide on Capitol Hill, describing Trump's press conference as "the craziest damn thing I've ever seen."

"When his party worked so hard to get this spending bill across the finish line -- at the very last minute -- and get essentially most of what he wants, and then to turn around and say he's going to veto it," Przybyla explained, "Katy, it's just a big temper tantrum."

"And you know why?" Przybyla asked rhetorically. "Because even though in terms most of the priorities of what he needs for the American people being in this bill, he lost big time on the wall."

"Let's also mention that Chuck Schumer (D-NY) offered to give Donald Trump that wall a couple of months ago in exchange for DACA, and Donald Trump said that was a bad deal," Tur reminded. "So he already negotiated away his leverage."

"So what he's getting is some fencing," Przybyla deadpanned, as Tur laughed. "He had to have his moment and threw a bit of a fit, but in the end, he really had no choice but to sign it."

"But to then, go ahead and make that statement, I can see why that Democratic aide sent that message," she concluded.
