Mazariego was scheduled to attend a luncheon meeting with Philadelphia labor leaders tomorrow. He was also to meet with me and with some of my colleagues during his monthlong stay in the United States. My office and other offices had been involved in an effort to win Mr. Mazariego a visa. which we heard Monday had been successful. However. just hours after obtaining his visa at the United States Embassy in San Salvador. Mr. Mazariego was arrested and charged with involvement in terrorist activity by the Salvadoran Treasury Police. a group which has been accused of having links to the notorious death squads.
