Senator Mitt Romney called for an end of the “vile, baseless” accusations promoted by Trump that then-Senator Joe Scarborough murdered one of his aides, Lori Klausutis, for the sake of her widower.

“I know Joe Scarborough. Joe is a friend of mine. I don’t know T.J. Klausutis. Joe can weather vile, baseless accusations but T.J.? His heart is breaking. Enough already,” Romney tweeted on Wednesday morning.
