COLUMBUS, Ohio - Considered to be on Mitt Romney's short list of potential running mates, Ohio Sen. Rob Portman was not chosen as the GOP front runner's running mate.
A Republican familiar with the situation told ABC News, Portman learned from Romney himself Friday night that he was not selected.
Romney instead chose Wisconsin Rep. Paul Ryan, who is also a Miami University Oxford alumnus.
Portman is in Columbus for the 2012 Pelotonia Race, a charity bike race that raises money for the Ohio State University Comprehensive Cancer Center.
Registered riders cover between 25 and 180 miles over one or two days of biking.
According to his rider profile, Portman is doing an estimated 50 mile trek from Columbus to Kenyon College in Gambier, Ohio. He is riding with his son, Will.
He also delivered remarks during the opening ceremony for the race, accompanied by Ohio State University President Gordon Gee.
Portman backed Romney early, endorsing the former governor in late January in South Carolina at a time when no clear front runner had emerged.
