NEW YORK (AP) -- The New York City hotel maid who says she was sexually assaulted by the head of the International Monetary Fund in his hotel room has picked him out of a police lineup.

The arraignment for Dominique Strauss-Kahn has been postponed until Monday. He was arrested Saturday on charges of a criminal sex act, attempted rape and unlawful imprisonment.

One of Strauss-Kahn's lawyers says their client denies any wrongdoing, and "intends to vigorously defend" the charges. Another lawyer says Strauss-Kahn has willingly consented to a scientific and forensic examination.

The IMF leader is getting strong support from his wife. Anne Sinclair, a New York-born journalist, says she doesn't believe "for one second" the accusations brought against her husband.

Unless the charges are quickly dropped, they could destroy Strauss-Kahn's chances in the French presidential race.
