NEW YORK (1010 WINS/AP) -- A federal investigation of Bernard Kerik, the former law enforcement heavyweight and protege of presidential hopeful Rudy Giuliani, appears to be drawing to a close with a possible indictment. A grand jury that has been hearing evidence in the case for several months was expected to vote on Thursday on whether to indict Kerik, a federal law enforcement official said Wednesday. If an indictment on tax evasion and other charges is handed up, Kerik would surrender Friday for arraignment in White Plains, N.Y., said the official, who spoke on condition of anonymity because the grand jury had not taken action. Asked Wednesday whether an indictment of Kerik was imminent, defense attorney Kenneth Breen said, "I haven't been told one way or the other.'' U.S. Attorney Michael Garcia's spokeswoman Yusill Scribner declined comment. The investigation of Kerik stemmed from a $240,000 renovation of his Bronx apartment in 1999. Authorities alleged most of the makeover was paid for by mob-connected builders who sought his help winning city contracts -- a charge he denied until a misdemeanor guilty plea in state court last year that spared him jail time and preserved his career as a security consultant. Before the apartment scandal broke, Giuliani had endorsed his old friend and former police commissioner's nomination in 2004 to head the Department of Homeland Security. But only days after President Bush introduced Kerik as his nominee, Kerik announced he was withdrawing his name because of tax issues involving his former nanny. A federal indictment of Kerik would cause a major headache for Giuliani as the first presidential primaries draw near. Giuliani frequently says that he made a mistake in recommending Kerik to be Homeland Security chief, but that might not be enough to avoid the political damage of a drawn-out criminal case involving his former loyalist. Giuliani, in an interview earlier this week with The Associated Press, argued that Kerik's woes shouldn't overshadow his administration's crime-fighting record. "There were mistakes made with Bernie Kerik,'' Giuliani said. "But what's the ultimate result for the people of New York City? The ultimate result for the people of New York City was a 74 percent reduction in shootings, a 60 percent reduction in crime. ... Sure, there were issues, but if I have the same degree of success and failure as president of the United States, this country will be in great shape.''
