"Nothing's happening for real people. Our democracy's been purchased," he continues.

“I like Tom personally, but I do have to say, as somebody who in this campaign has received 2 million contributions, averaging $19 a person, I'm a bit tired of seeing billionaires trying to buy political power,” Sanders told MSNBC.

Warren shared the Vermont senator's sentiments.

“The Democratic primary should not be decided by billionaires, whether they’re funding Super PACs or funding themselves,” Warren added in a tweet. “The strongest Democratic nominee in the general will have a coalition that’s powered by a grassroots movement.”
