As of 12:28 p.m., he's Sen. Rubio
Marco A. Rubio was sworn in at 12:28 p.m. as Florida's new U.S. Senator.
The 39-year-old Republican from Miami walked down the aisle with former Sen. Mel Martinez to his right and Sen. Bill Nelson to his right. Vice President Joe Biden admistered the oath of office and Rubio then signed the oath of obligation.
Rubio, clutching his Bible, flashed a big smile and shook hands with members of the body. Then he took his seat in the back row of the Republican side of the chamber.
