The charges of Samper's corruption arose from disclosure of tape recordings between Cali drug lords and Samper campaign aides, and allegations by Samper's 1994 campaign manager and treasurer. Colombia's chief prosecutor, Alfonso Valdivieso, charged Samper with illicit enrichment, falsifying documents, electoral fraud and obstruction of justice. Samper conceded that tainted money had entered the campaign, but claimed that he was unaware of it and was therefore not guilty. For more background information, see the February 1996 and March 1996 issues of NewsBriefs . Samper's absolution had been expected by most observers because Samper's Liberal Party dominates Congress, and over two dozen of the 165 House members are under investigation themselves for alleged corruption.
Critics complain that the investigation was corrupted and lacked depth.
Leaders in the Roman Catholic Church, leading businessmen, the media, and political leaders are now calling for Samper's resignation. In addition, Colombian leaders worried that the decision would sour relations with the United States even further. During the weeks leading up to the vote, U.S. officials said they were considering sanctions against Colombia such as recessions of preferential trade tariffs, revoking landing rights for planes, and canceling visas for political leaders. In a secret cable dated June 12, hours before the Samper vote, the U.S. embassy explained its anti-Samper plans. For more information on that report, see the April 1996 issue of NewsBriefs .
