Marc Thiessen has this column in the WaPo:
[Attorney General Jeff] Sessions is the victim of the type of McCarthyite character assassination that the left used to condemn. Remember when accusing people without evidence of coordinating with the Kremlin was frowned upon? No longer, apparently.
In fact, what Sessions faced may be worse than McCarthyism. At least McCarthy was right when he claimed that there were Russian spies in the State Department (see Hiss, Alger, among others). On "Meet the Press" this weekend, former Obama director of national intelligence James R. Clapper Jr. declared that the U.S. intelligence community he headed until a few weeks ago had found "no evidence" of any collusion between members of the Trump campaign and Russian intelligence. No evidence.
