Joe Biden encourages Mitt Romney to run for Senate

During a private event Friday night in Park City, Biden called Romney a man of integrity and said he should mount a challenge next year, according to a person in the room.

“By the way, you should run for Senate,” one attendee quoted Biden as saying. The comment was quick and off-hand, but the crowd of Romney loyalists appreciated it and applauded.

The two men were on opposite sides of the 2012 election — Biden as the running mate of President Barack Obama and Romney as the Republican presidential nominee.
