DAYTON, Ohio (CNN) - It is unclear if John McCain has notified his running mate yet, but planned Denver media appearances by Minnesota Governor Tim Pawlenty, thought to be a top contender, were abruptly canceled Thursday so he could back to head back to Minnesota, an aide said.
Pawlenty’s appearances were canceled by the Republican National Committee, which had invited him to Denver to act as a McCain surrogate during the Democratic convention.
Another VP contender, former primary season rival Mitt Romney, is traveling in California and attending private events, including fundraisers. There was no indication he has received word either way yet from McCain, according to sources close to the former Massachusetts governor.
A Republican source close to McCain also says not to rule out former eBay CEO and McCain economic adviser Meg Whitman. Independent Senator Joe Lieberman is also considered a major contender for the VP slot on the GOP ticket.
A senior McCain adviser has told CNN the presumptive Republican presidential nominee has made his final decision on his running mate. Republican sources told CNN he settled on his choice Wednesday night, while the McCain adviser insists the candidate finalized his choice Thursday morning.
