I’m telling you, Katherine Harris is a VH-1 celeb-reality show waiting to happen:

U.S. Senate candidate Katherine Harris received a grand jury subpoena from federal investigators but kept it from her top campaign advisers, leading to the latest round of staff departures last month, a former aide said.

“Yes, there was a subpoena. She didn’t tell us,” former campaign manager Glenn Hodas told The Tampa Tribune for a story published Wednesday.

Hodas, who resigned from the Republican congresswoman’s Senate campaign in July along with the spokesman, did not immediately return phone calls Wednesday from The Associated Press.

The Justice Department is investigating Harris’ dealings with Mitchell Wade, a defense contractor who later pleaded guilty to bribing another congressman. Hodas did not say whether the subpoena was linked to that probe.

Harris was reached on her cell phone Wednesday by The Associated Press, but said she had a bad connection and referred the call to her campaign office.

Campaign spokeswoman Jennifer Marks on Wednesday repeated an earlier statement that said Harris is cooperating with the investigation but is “not a target,” and declined to comment further.

Marks declined to answer a question about whether Harris received the subpoena and said Harris would not be available to comment because her personal schedule was too busy.

How many staff rotations is this, anyway? I think Ed Rollins was the first campaign manager and there have been at least two since he quit. Anyone keeping score?
