US congressman Mr Gary Condit has been urged to take a lie dectector test by the parents of missing intern Ms Chandra Levy.
The parents of Ms Levy asked the congressman to take the test as a sign of "good faith", after he misled them about his intimate relationship with the 24-year-old California woman, the family's lawyer said.
Mr Condit told Ms Levy's mother he was not having an affair with the young woman and that he had last seen her on April 24th or April 25th. But he reportedly later acknowledged he was intimate with Ms Levy and that they had last seen each other April 29th, a day before she disappeared, lawyer Mr Billy Martin said.
"The family does not credit what congressman Condit says. They've asked as a sign of good faith, take a polygraph," Mr Martin said. "We believe the congressman has been less than truthful in representing his relationship with Chandra."
Mr Martin said the family had evidence Ms Levy was intimately involved with Mr Condit, a 53-year-old married father of two. Mr Condit is not a suspect in the Levy case.
In two interviews with Washington police, Mr Condit reportedly said he and Ms Levy were friends. But in a hastily arranged third interview on Friday, Mr Condit confirmed the two had an affair, according to published reports.
Mr Martin said he had sent a letter yesterday asking the Democratic congressman to take a lie detector test and answer questions about his relationship with Ms Levy, how they met, and her state of mind at the time she disappeared 11 weeks ago.
Mr Condit's lawyer told reporters his client would comply fully with police investigating Ms Levy's disappearance, including allowing a search of his apartment, providing telephone records and submitting to a DNA test.
