COLUMBUS, Ohio (AP) -- Vice President Joe Biden is postponing his planned trip to Tampa, Fla., the site of the Republican National Convention.

An Obama campaign official says Biden is putting off Monday's trip in order to ensure that all local law enforcement and emergency management resources can stay focused on Tropical Storm Isaac, which could impact Florida during the convention.

Biden had planned a two-day swing through Florida during the Republican meetings to counter their message. The official says Biden still plans to continue with stops in Orlando and St. Augustine, Fla., on Tuesday.

The official wouldn't say whether Biden would reschedule his stop in Tampa, only that the campaign was monitoring the storm. The official requested anonymity in order to speak ahead of the campaign's official announcement.
