WASHINGTON — Senate Republican Leader Mitch McConnell briefly left his own press conference Wednesday after stopping his remarks mid-sentence and staring off into space for several seconds.

       McConnell approached the podium for his weekly press conference and began speaking about the annual defense bill on the floor, which he said was proceeding with “good bipartisan cooperation.” But he then appeared to lose his train of thought, trailing off with a drawn-out “uh.”

       The Kentucky senator then appeared to freeze up and stared vacantly for around 20 seconds before his colleagues in Republican leadership, who were standing behind him and could not see his face, grabbed his elbows and asked if he wanted to go back to his office.
