Some Republicans Smear Alexander Vindman

Disgusting--though it seems to have been Sean Duffy, Rudy Giuliani, and Laura Ingram. Contra the NRO, that's not "Congressional Republicans."
Yoo's explanation of his comments makes perfect sense. He was not smearing Vindman, he was suggesting that the Ukrainians may have been conducting espionage on us. If someone says something importantly ambiguous, they have the right to disambiguate it.
