The Trump administration is welcoming right-wing media stars to the White House today for a forum billed as a “social media summit.” Among those invited to attend are Bill Mitchell, a self-described member of the “Trump Train” who’s embraced the far-right QAnon conspiracy theory, and Ali Alexander, a far-right activist whose recent tweet smearing Senator Kamala Harris as “not an American Black” was retweeted—then deleted—by Donald Trump Jr. Also joining will be James O’Keefe, a discredited right-wing activist known for targeting Planned Parenthood and ACORN. O’Keefe was infamously arrested for trying to wiretap the office of the former U.S. senator from Louisiana, Mary Landrieu.
