How Mueller Has Swayed Democrats on Impeachment

Philip Bump: “As of writing, 109 House Democrats have publicly endorsed impeaching President Trump. That ‘as of writing’ is important, because new converts to the cause have been popping up frequently over the past few days — pushed, it seems, by former special counsel Robert Mueller’s testimony on Capitol Hill last week.”

“For a long time, the pro-impeachment caucus was modest, making up less than a dozen of the members of the Democratic caucus. Since Mueller concluded his work in March, new endorsements have come in bunches, with surges after each time Mueller offered his views to the world: With the release of the report, at his late-May press briefing and with last week’s testimony.”
