Federal drug and perjury charges against a friend of Mayor Marion Barry Jr. raise new questions about the mayor's ability to lead the city's anti-drug war.

Charles Lewis, 48, a former city employee, was charged in a 10-count indictment Thursday with lying to a grand jury seven times about whether he used cocaine. He also faces three counts of cocaine possession.It is the second time in five years that an associate of the mayor's has faced drug charges.

"It heightens the circumstantial perception that there's more there than we've been told," said Rep. Stan Parris, R-Va., an outspoken critic of the Barry administration. "When do you reach the point where you can conclude that where there's smoke, there's fire?"
