O'Malley tunes up for presidential announcement

We're getting the distinct impression that Martin O'Malley will indeed confirm Saturday that he is running for president.

A day before his announcement at Baltimore's Federal Hill Park, the O'Malley campaign released a video Friday of the former Maryland governor tuning up his guitar.

He then strums the opening notes of a familiar song: "Hail to the Chief."

"Stay tuned," the video said.

O'Malley is scheduled to make his announcement at 10 a.m. Saturday.
