Senate Republicans have hired an attorney to use as a questioner of Christine Blasey Ford at Thursday’s high-stakes hearing on sexual assault allegation against Supreme Court nominee Brett Kavanaugh but are declining to name her.

Judiciary Chairman Chuck Grassley (R-Iowa) told POLITICO on Tuesday as he entered the Capitol for a weekly GOP meeting that “we aren’t announcing the name for her safety.” Asked if Republicans have received any indication of threats to the attorney they’re preparing to use, Grassley said: “I don’t know, but I guess we’re just being cautious.”
