Patti Blagojevich's Family Defend Tarnished Illinois First Lady (VIDEO)

Lady Macbeth. Carmela Soprano. Potty mouth.

Patti Blagojevich is not any of those, her family said Wednesday.

"That is absolutely not my sister," Deborah Mell told the Chicago Sun-Times and NBC5 in an exclusive interview. "Patti is a mother, a sister and a devoted wife.

"She is particularly protective of her family."

So what about the profanity-laced tirade allegedly recorded by the feds and beamed around the world after Tuesday's arrest of her husband, Gov. Blagojevich?

Mell, a newly elected state representative; her father, Ald. Dick Mell (33rd), and brother Rich Mell said those statements aren't representative of the first lady's personality. They acknowledged, though, that she has been stuck in a "pressure cooker" caused by federal investigations of her husband.

The Mells agreed to gather in the living room of Ald. Mell's Northwest Side home to try to set the record straight about the first lady's image.
