Police Search Condit Apartment

W A S H I N G T O N, July 10 -- Police have entered the apartment of Calif. Rep. Gary Condit to search for clues to the disappearance of missing intern Chandra Levy.

Police unloaded gear and entered the back door of Condit's apartment building shortly before 11 p.m. ET, and remain inside the building.

Several reports say Condit is in the apartment with police, but that could not be immediately confirmed.

Police Chief Charles Ramsey told reporters earlier in the day that investigators asked for all of the things Condit's lawyer, Abbe Lowell, offered on Monday — including DNA samples and access to the California congressman's Washington apartment.

Lawyer Says Condit Willing to Comply

Shortly before the search began, Lowell's spokesman released a statement reiterating the congressman's willingness to comply.

"Mr. Lowell would not have made the offer he made last night if it were not serious," spokeswoman Marina Ein said. "The police have taken them up on that offer and the details will be worked out."

Still unclear is whether Condit will take a polygraph test. Ramsey said he has asked Condit to take an FBI-administered test. Levy's parents and their lawyer have called on Condit to take such a test. But Lowell has said only that his client would consider such a request if police asked. In so doing, however, he discounted the effectiveness of lie detector tests.

Ramsey today defended the technology and said any test of Condit would be conducted by "world-renowned" FBI experts.

"We all understand the limitations of the polygraph but … it's a good investigative tool," Ramsey said.

Law enforcement sources tell ABCNEWS that police have administered polygraphs to two male acquaintances of Levy, but they are not considered suspects. Both did well on the tests and the sources made clear the two don't appear to have any information about her disappearance.

Flight Attendant to Talk to Investigators

Amid these developments, a flight attendant who claims Condit tried to get her to lie about an affair is headed to Washington as investigators consider whether the congressman may have tried to obstruct justice in the search for Levy.
