MSNBC host Rachel Maddow did not appear to believe her ears when colleague Lawrence O'Donnell shared with her the announcement made by Democratic congressional leaders Wednesday evening that they had reached an agreement to exclude the border wall from a deal on the Deferred Action for Childhood Arrivals program after dining with President Trump.

As Maddow was handing off to O'Donnell at the top of the 10 o'clock hour, O'Donnell said he had "breaking news" and asked Maddow to try and help him figure it out.

Putting on his glasses, O'Donnell read the joint statement put out by Senate Minority Leader Chuck Schumer, D-N.Y., and House Minority Leader Nancy Pelosi, D-Calif.:

"We had a very productive meeting at the White House with the President. The discussion focused on DACA. We agreed to enshrine the protections of DACA into law quickly, and to work out a package of border security, excluding the wall, that's acceptable to both sides. We also urged the President to make permanent the cost-sharing reduction payments, and those discussions will continue."

"The president according to this caved on the wall," O'Donnell added afterwards.

A skeptical Maddow then asked, "The phrasing there is we came to an agreement?"

"Yes! An agreement," O'Donnell said, before offering: "It's worth going over again."

Following the reread, Maddow was still someone wary, suggesting that perhaps Pelosi and Schumer used tricky wording and meant they had agreed among themselves, and not with Trump, "in which case that's not much news."

Otherwise, she admitted, "this could potentially be a big deal."

But she cautioned: "I am disinclined to believe anything that Donald Trump says about his own future behavior or that anybody else says that Donald Trump has committed to anything about his own future behavior until I actually see the behavior."

After the Schumer-Pelosi statement came out, a short tweet from White House press secretary Sarah Sanders denied that a deal on excluding the wall had been made.

"While DACA and border security were both discussed, excluding the wall was certainly not agreed to," she tweeted.
