2020 presidential candidate Bernie Sanders on Sunday lobbed a warning to the "corrupt, greedy corporate elite" who received tax breaks under President Trump, saying they'd better "spend that money quick" before he rescinds the legislation.

"The first thing that we are going to tell them is that Trump and his friends may have given them over a trillion dollars in tax breaks, but they had better spend that money quick," Sanders said at a town hall in Dover, New Hampshire. "Because we are going to... rescind those tax breaks as soon as we get into office."
