(CNN) - Former GOP presidential running mates Mitt Romney and Paul Ryan met Thursday morning in a Washington hotel, a Republican official told CNN.

The meeting ended around 11 a.m. ET, the official said. Following the meeting, Ryan issued a statement saying he was "grateful to Governor Romney for the honor of joining his ticket this fall, and I cherish our friendship."

"I'm proud of the principles and ideas we advanced during the campaign and the commitment we share to expanding opportunity and promoting economic security for American families," Ryan continued in the statement.

A Ryan aide said the meeting was "constructive and positive," and focused both on reflections from the campaign and on upcoming fiscal and economic challenges for the country.
