A hard drive recovered from the computer of a killed Colombian guerrilla has offered more insights into the opposition of House Democrats to the U.S.-Colombia Free Trade Agreement.

A military strike three weeks ago killed Raúl Reyes, No. 2 in command of the FARC, Colombia's most notorious terrorist group. The Reyes hard drive reveals an ardent effort to do business directly with the FARC by Congressman James McGovern (D., Mass.), a leading opponent of the free-trade deal. Mr. McGovern has been working with an American go-between, who has been offering the rebels help in undermining Colombia's elected and popular government.

Mr. McGovern's press office says the Congressman is merely working at the behest of families whose relatives are held as FARC kidnap hostages. However, his go-between's letters reveal more than routine intervention. The intervenor with the FARC is James C. Jones, who the Congressman's office says is a "development expert and a former consultant to the United Nations." Accounts of Mr. Jones's exchanges with the FARC appeared in Colombia's Semana magazine on March 15. This Mr. Jones should not be confused with the former Congressman and ambassador to Mexico of the same name from Oklahoma.

"Receive my warm greetings, as always, from Washington," Mr. Jones began in a letter to the rebels last fall. "The big news is that I spoke for several hours with the Democratic Congressman James McGovern. In the meeting we had the opportunity to exchange some ideas that will be, I believe, of interest to the FARC-EP [popular army]."

Mr. Jones added that "a fundamental problem is that the FARC does not have, strategically, a spokesman that can communicate directly with persons of influence in my country like Mr. McGovern." Semana reports that in the documents Mr. Jones "rules himself out as the spokesman but offers himself as a 'bridge' of communication between the FARC and the congressman." Semana says when it spoke with Mr. Jones, he verified the letter and explained that "he made the offer because the guerrillas need interlocutors if they want to achieve peace and that it is a mistake to isolate them."
