U.S. Senate Republican leader Mitch McConnell briefly froze during remarks to reporters on Wednesday and was escorted away from the press conference. After returning to the news conference, McConnell was asked by reporters if his absence was related to a concussion he sustained in March, when he was hospitalized for a few days after tripping and falling, and if he had anyone in mind to replace him when he is no longer leader. McConnell walked away without giving a clear answer.
