NORFOLK, Va. – Republican presidential candidate Mitt Romney has decided on a running mate and will announce his decision Saturday morning in Norfolk, Va., his campaign said Friday night.

Romney advisers wouldn't disclose the name.

In a statement issued Friday night, the campaign would only go so far as to say that the running mate would be revealed at 8 a.m. Central Time at the start of a four-state bus tour at the Nauticus Museum. Berthed at the museum is the USS Wisconsin – possibly a hint about Romney's choice.
