Sen. Ted Cruz (R-TX) slammed his Republican colleagues on Friday for failing to denounce Tucker Carlson amid the fallout from the conservative pundit’s interview with Nick Fuentes, a white nationalist who has contributed to the recent rise in antisemitism online.

“My colleagues, almost to a person, think what is happening is horrible, but a great many of them are frightened because he has one hell of a big megaphone,” Cruz said of Carlson at the Federalist Society’s National Lawyers Convention in Washington, D.C.
