(CNN) Sen. Bernie Sanders has accused a leading liberal think tank, founded and run by longtime Hillary Clinton allies, of orchestrating attacks on him and two other 2020 Democratic presidential candidates. In a letter provided to CNN by his campaign, Sanders addressed the board of the Center for American Progress and CAP Action Fund on Saturday, alleging that its activities are playing a "destructive role" in the "critical mission to defeat Donald Trump." Sanders cited two posts about him by ThinkProgress, a website run by CAP's political arm, and past pieces focused on Sens. Elizabeth Warren and Cory Booker. Saturday's letter from Sanders follows ThinkProgress' publication of a video last week suggesting Sanders had altered his message, which has long singled out "millionaires and billionaires," after becoming a millionaire himself.
