WASHINGTON (August 1, 2012)--Mitt Romney's campaign is finalizing plans for a multistate bus tour that will begin late next week and is expected to include stops in Virginia, North Carolina and Florida, although the schedule may change in the coming days.

Romney returned from a bumpy overseas trip late Tuesday and was spending Wednesday in meetings at his Boston campaign headquarters.

Romney is scheduled to campaign Thursday in the Denver area and aides say he'll attend a Republican Governors Association fundraiser in Aspen later that night.

A handful of governors who are often mentioned as possible Romney running mates are scheduled to attend.

Next week's bus tour could be part of the rollout for a running mate.

Republican officials are expecting that announcement any day.
