Rumored Romney VP pick Rubio cancels Philly book event Wednesday

Talk Radio 1210 AM host Dom Giordano's book event and conversation tonight with U.S. Sen. Marco Rubio (R-FL) scheduled for Wednesday night at the National Constitution Center has been postpoed indefinitely, the radio station announced this afternoon.

"Sen. Rubio was called back to Washington to take part in unexpected votes in the Senate," says 1210 on its website before apologizing to ticketholders of the sold-out event which cost $25 and included a copy of the rumored potential Mitt Romney VP candidate's new book "An American Son."

Rubio canceled a scheduled appearance Tuesday night on Comedy Central's "Daily Show with Jon Stewart." On Tuesday  ABC News and the Washington Post reported that Rubio was not being vetted by the Romney campaign and later in the day Romney said that Rubio was in fact being vetted by his team.

Either way, Rubio who gives lots of interviews, certainly seems to be avoiding public appearances the past few days.

Rubio's press secretary Alex Conant got back to us and said the Constitution Center event was canceled due to Senate voting.

"The VP speculation had nothing to do with it," Conant wrote.

"We were able to reschedule a couple of the interviews for studios in DC (he did two FOX News interviews last night and was on CBS this morning). We are rescheduling the Daily Show for next week, since they could only take us if we were in studio," Conant wrote Wednesday afternoon.
