LITTLE ROCK, Ark., May 21 (UPI) -- The Justice Department has agreed to drop obstruction of a congressional investigation charges against President Clinton's old friend Charlie Trie in exchange for his guilty plea to two federal election law violations and a promise of cooperation. Trie agreed to the plea bargain today in U.S. District Court, pleading guilty to causing a false statement to be made to the Federal Election Commission and making a political contribution in the name of another. Trie was charged with causing the treasurer for the Democratic National Committee to make a false report to the FEC by lying about the origin of a political contribution Feb. 19, 1996. As part of the seven-page plea agreement, Trie agreed to ``fully cooperate'' with the Justice Department in its investigation into the political campaign fund-raising case, including the taking of polygraph tests. The false statement charge is a felony with penalty of up to five years in prison and a maximum fine of $250,000. The second charge is a misdemeanor offense with a possible one year in prison and a maximum $100,000 fine. U.S. District Judge George Howard Jr. scheduled sentencing for Aug. 12. The Justice Department agreed to drop the obstruction charge and the rest of a 15-count indictment returned in Washington, D.C., in the case. The obstruction charge related to a single phone call Trie allegedly made nearly two years ago from Hong Kong to his assistant in Little Rock. Prosecutors said Trie told his assistant to ``get rid of'' records subpoenaed by a Senate committee investigating alleged fund-raising abuses in Clinton's 1996 re-election campaign. Defense attorney Reid Weingarten disputed the allegations that Trie obstructed a congressional investigation. He said investigators got all the documents they asked for in their probe. A grand jury in Washington returned the indictment in January 1998, and the obstruction charge was one of the charges in that indictment. It was re-filed in Little Rock after being dismissed in Washington for improper venue. Weingarten said Trie was the owner of a popular Chinese restaurant in Little Rock where then-Gov. Clinton used to eat with other politicians and the two men developed a friendship over the years.
