evidence: Sen. Bernie Sanders said on ABC's "This Week" Sunday that he believes "the establishment" forced Sen. Amy Klobuchar and Pete Buttigieg out of the 2020 presidential race to ensure that voters "coalesced" around Joe Biden in order to defeat him. [...] We are taking on, as I think everybody knows, the establishment. We are taking on the corporate establishment. We're taking on the political establishment. And what you are seeing now, just in the last few weeks, is Wall Street, the health care industry, the billionaire class putting a lot of money into Joe's campaign. But at the end of the day, you know what? I think we're going to win this thing." Lis Smith, senior communications adviser for the Buttigieg campaign, responded to Sanders' comments in a tweet Sunday, saying Buttigieg's "decision to get out of the race was his and his alone."
