ORLANDO, Fla. -

A Florida congressman is accusing his wife of bigamy in divorce papers.

U.S. Rep. Alan Grayson said in papers filed last week that his wife of almost 24 years, Lolita, was married to another man at the time she married the congressman in 1990.

Grayson said he was unaware  that his wife was still married when they wed.

The Democrat from the Orlando area said his wife secretly divorced her other husband in 1994.

An attorney for Lolita Grayson, Mercedes Wechsler, wouldn't comment on the court papers Tuesday.

Earlier this year, Lolita Grayson accused her husband of pushing her during a confrontation at their home, but sheriff's investigators found no probable cause.

The Graysons have five children, and the congressman is seeking parental responsibility for the four minor children.
