ABC News senior political correspondent Jonathan Karl is reporting that Sen. Marco Rubio (R-FL), widely assumed to be at the top of anybody’s list of vice presidential candidates, is not being vetted by Romney’s vice presidential search team.

Karl reported on “Good Morning America” that Republican sources told him Rubio has not been asked to complete any questionnaires or been asked to turn over any financial documents typically required of potential vice presidential candidates.

Rubio, a charismatic campaigner whose Cuban roots could help attract Latino voters to the Republican ticket, has long thought to be one of the top contenders for the nomination.

In his report for ABC, Karl wrote: “Although it is possible that Rubio may yet be asked to go through the vetting process, it has been nearly two months since Romney named his long-time aide Beth Myers to run vice presidential search. The fact that Rubio has not been asked to turn over any documents by now is a strong indication that he is not on Romney’s short list of potential running mates.”

Neither Romney nor Rubio had any comment on the report.
