Attorneys for flight attendant Anne Marie Smith, who alleges that she had a 10-month affair with U.S. Rep. Gary Condit, asked a California grand jury on Monday to indict the embattled congressman, saying he had obstructed a probe into the disappearance of federal intern Chandra Levy. Details of an alleged affair between Smith and Condit emerged during the investigation into the Levy's disappearance in Washington, D.C. "What we are doing is requesting the grand jury or the district attorney to conduct an investigation," Ernie Norris of Judicial Watch, a conservative watchdog group that filed the complaint, told Reuters. "We believe we have the evidence right at hand, right here, that is sufficient to indict." Smith has said publicly that Condit asked her through his lawyers to sign an affidavit denying the affair ever took place. Speaking to Connie Chung during a Thursday TV interview, Condit, 53, denied the relationship with Smith, saying, "I didn't ask anyone to lie about anything. I did not ask Anne Marie not to cooperate with law enforcement. That's an absolute lie." As he told PEOPLE about Smith: "She does this for her own publicity." Monday's complaint also sought indictments of Mike Lynch, Condit's chief of staff, and Don Thornton, an investigator, for obstruction of justice and conspiracy to suborn perjury in connection with the alleged attempts to secure Smith's silence. Meanwhile, Smith's attorney, James Robinson, told reporters at a news conference that the decision to seek a criminal probe of Condit did not mean that he was giving up the option of a civil case against the congressman, whom he has accused of libeling and slandering his client. In addition, NBC News has reported that California Gov. Gray Davis has requested that Condit not seek re-election. On Monday night, Condit's son, Chad Condit, told Larry King on CNN that he will urge his father not to run again, even though he believes the congressman has "done nothing to resign for. My family vote would be that he doesn't (run). I don't think that he deserves this."
