"I believe that Donald taps into a deep anger that the American people feel and rightly feel," Warren told CNBC's "Power Lunch." "I think people all across this country understand what's broken about this economy, what's broken about this country, that we now have a Washington that works for those who can hire armies of lobbyists and lawyers but its not working for the rest of America. The problem is that Donald Trump will just take us in the wrong direction."
Warren's comments follow months of barbs between the Democratic senator from Massachusetts and Trump, the Republican presidential nominee. She also bashed Trump for his plans to roll back regulations on big banks.
Warren has repeatedly called for more oversight of large financial institutions and was instrumental in the creation of the Consumer Financial Protection Bureau. She discussed the Wells Fargo fake account scandal and consumer protection during the interview, contending Trump would set back progress on regulation.
"His view, for example, on the whole banking crisis that we've been talking about is let's further deregulate the banks," Warren said.
Warren, a popular figure in the progressive wing of the Democratic Party, previously endorsed the more moderate Hillary Clinton for president. Warren said that Clinton has adopted a more "progressive agenda" and said she would do "everything (she) can to help her get elected."
