Why does President Clinton want to send an ambassador to Mexico who supports the medical use of marijuana, a position opposed by his own White House drug czar? . . . . That is the question 12 Republican congressmen are raising in a letter to Mr. Clinton, urging him not to nominate William Weld, the Republican governor of Massachusetts. . . . . It remains to be seen how effective the House members will be in influencing the debate because the Senate is the only chamber that has the authority to confirm or reject ambassadorial nominations. . . . . Pointing out that 80 percent of the marijuana smuggled into the United States comes through Mexico, the congressmen said: . . . . "Given Mexico's difficulty in controlling narcotics trafficking across its borders, we strongly believe that sending an ambassador who ... endorses the use of an illegal drug ... undermines American efforts to curb the flow of drugs into our country and undercuts the chief executive branch official in charge of prosecuting the drug war, Gen. Barry McCaffrey." . . . . Mr. Weld could not be reached for comment yesterday. A White House spokesman said Mr. Clinton has not nominated Mr. Weld. The president, however, has made it clear he wants the governor to take the position, and Mr. Weld has said he wants the job. . . . . "He has not been nominated," White House spokesman Barry Toiv said yesterday. "If and when that occurs, the Senate will have ample opportunity to ask him any questions they may have." . . . . Mr. Weld last year signed a state law authorizing the use of marijuana for certain medical conditions, a position strongly opposed by Gen. McCaffrey, the director of the White House Office of National Drug Control Policy. . . . . The letter, released last week, was organized by Rep. Mark Souder of Indiana, vice chairman of the House Government Reform and Oversight subcommittee on national security, international affairs and criminal justice. The panel has oversight over Gen. McCaffrey's office. . . . . Others signing the letter were Republican Reps. Tom Coburn, Lindsey Graham, Van Hilleary, John Hostetller, Bill McCollum, David McIntosh, John Mica, Vince Snowbarger, Bob Stump, Todd Tiahrt and Dave Weldon.
