ABC News' Kate Snow reports: Sens. Barack Obama and Hillary Clinton held a secret meeting at the home of Sen. Dianne Feinstein, D-Calif., Thursday evening in Washington.
Feinstein is an early Clinton supporter who lately has been advocating for a joint Obama-Clinton ticket.
In an unexpected and unprecedented move for the candidate, Obama, D-Ill., shed his traveling press corps as they got on the plane with the understanding that Sen. Obama would join after his local interviews.
Right before take off, the press corps was informed Obama would not be flying to Chicago. Instead, he will be spending the evening in Washington.
Communications director Robert Gibbs told the press corps, "He is not going to be in D.C. tonight for awhile, so he wanted to schedule meetings."
When asked if those meetings involve Clinton, Gibbs was coy and responded, "I'm not going to discuss what he's going to do."
