Sen. Claire McCaskill (D., Mo.) said her campaign was "hitting the road" in an RV to tour the state, but public flight information indicates that travel also occurred on her million-dollar private plane.

The RV, named BigBlue by the campaign, was unveiled late last month by McCaskill, who said she was "very excited to hit the road" in it for an upcoming "Veterans for Claire" tour. The campaign kept a live blog of its three-day RV trip from May 29 to May 31, posting updates of its whereabouts.
