Sen. Elizabeth Warren on Monday blasted President Trump on his first 100 days performance since taking office.

The Massachusetts Democrat gave the president an "F" for not living up to his campaign promises to help America's working people. "He's a man who ran for office promising he was going to be there to help working people. That was going to be his No. 1, No. 2, No. 10 goal, right all the way through," Warren said in an interview with CNN host Jake Tapper.

"[S]o what has he done? First, he assembles a team of billionaires and bankers and hands the keys over to them, says to Goldman Sachs, 'you figure out hot to deregulate the economy.' I mean, what could possibly go wrong," she exclaimed.

Warren then criticized Trump's flurry of executive orders. "[H]e signs off on all these executive orders. ... He signed off on one that makes it easier for government contractors to cheat their employees out of their wages ... he makes it easier for investment advisers to cheat retirees."

Trump has signed more than 37 executive orders since January.

But the executive order that sums it all up for Warren is the issue of repealing and replacing Obamacare. "The one that summarizes it all was Trumpcare. When he embraces this healthcare plan that says he's gonna go all in," she said.

The three main features of Trumpcare — knocking 24 million off healthcare, raising costs for middle-class families and providing tax cuts for the wealthy — affect the working class people the most. "He promised to deliver for America's working people and what he's delivered is a gut-punch" to America, Warren said.
