Senate Minority Leader Chuck Schumer, D-N.Y., said Wednesday President Trump has "no understanding" of a deal struck by Sens. Lamar Alexander, R-Tenn., and Patty Murray, D-Wash., after he came out against the agreement.

After praising the negotiations between the two senators, Schumer went after Trump for tweeting he could "never" support bailing out the insurance companies, saying he doesn't know what he is talking about and should do some research before he tweets.

"Frankly, the president doesn't know what he's talking about," Schumer said on the Senate floor, arguing the two senators' deal makes clear that the money would not go to insurance companies. "The president ought to know what he's talking about when he tweets about bills because on this one, he had no understanding of what it's about. This helps people, millions of people."

The longtime New York Democrat also said the president's "zigging and zagging" is hurting his presidency and his ability to effectively govern. Particularly, he took aim at Trump's push in recent weeks for an agreement to fund the cost-sharing reduction payments through the end of 2018, including calling the deal a "very good solution" during a press conference in the White House Rose Garden.

"He's totally inconsistent. For it one day, against it the next day. You cannot govern a country. You cannot keep America great if you don't know what's in the bills and don't have a consistent policy about them. But he keeps zigging and zagging," Schumer said. "Our only hope is maybe tomorrow he'll be for this again."

Schumer lauded the negotiations between Murray and Alexander, who had been working on the proposal since September.

"Like all good negotiations, both sides gave some, both sides got some. The product is something neither side is completely happy with, but both sides can move forward with. That's what a good fair compromise looks like," Schumer said, adding it was a "nice bipartisan flame."
