And yet another wheel comes off the bus:

In Omaha for a closed to the press fundraiser for her husband Friday, Mrs. Romney was supposed to give interviews to several reporters but canceled due to the controversy over her blow up at Republicans on a radio interview, in which she ordered Mitt’s Republican critics to “stop it.”

Omaha.com reported:

She had scheduled interviews with The World-Herald and other reporters but canceled after controversy erupted this week over her comments to a public radio station in Iowa about her husband’s Republican critics.

She appeared at the luncheon, $250-per-plate fundraiser at the Embassy Suites and La Vista Conference Center. The event was closed to reporters.

So much for being Mitt's secret weapon.
