Former New York City Mayor Michael Bloomberg shot back at criticisms that he's running a self-aggrandizing campaign for the Democratic nomination, telling Reuters in an interview: "Number one priority is to get rid of Donald Trump. I’m spending all my money to get rid of Trump."

The campaign finance debate has taken on new significance in 2020, creating a clear divide within the Democratic Party. Progressive candidates like Sens. Bernie Sanders and Elizabeth Warren have turned away big-dollar donations in favor of grassroots fundraising, rebuking moderates like Pete Buttigieg and Joe Biden for soliciting donations from the wealthy.
