President Barack Obama is bringing out the big dog.

The president's re-election campaign announced Thursday that former President Bill Clinton will join Obama on the campaign trail Monday, at events in Orlando, Fla., Youngstown, Ohio and Prince William County, Va.

Clinton has been one of Obama's biggest surrogates this cycle, stumping for him on the campaign trail, appearing in ads for the president, and giving the high profile nominating address at the Democratic National Convention in Charlotte, North Carolina last month.

While they've appeared together at fundraisers, and of course, their well-documented hug at the convention, Monday will mark the first time the two men will have teamed up at a campaign rally.

Florida, Ohio, and Virginia are arguably the three most important battleground states, with a combined 60 electoral votes at stake.
