Uh oh. This is not going to be a good day for Mittens:

For Mitt Romney, it's one scary Halloween. The Presidential candidate has just learned that tomorrow afternoon he will be charged by the United Automobile Workers (UAW) and other public interest groups with violating the federal ethics in government law by improperly concealing his multi-million dollar windfall from the auto industry bailout.

At a press conference in Toledo, Bob King, President of the United Automobile Workers, will announce that his union and Citizens for Responsibility and Ethics in Washington (CREW) have filed a formal complaint with the US Office of Government Ethics in Washington stating that Gov. Romney improperly hid a profit of $15.3 million to $115.0 million in Ann Romney's so-called "blind" trust.

The Nov. 1, 2012 press conference is scheduled for 2 p.m. EST at the UAW on Ashland Ave., Toledo, Ohio.
