Randy Glass.
Randy Glass.
Randy Glass, a former con artist turned government informant, later will claim that he contacts the staff of Senator Bob Graham and Representative Robert Wexler at this time and warns them of a plan to attack the WTC, but his warnings are ignored. Glass also tells the media at this time that his recently concluded informant work has “far greater ramifications than have so far been revealed,” and, “potentially, thousands of lives at risk.” Glass was a key informant in a sting operation involving ISI agents who were illegally trying to purchase sophisticated US military weaponry in return for cash and heroin. He later claims that in July 1999, one ISI agent named Rajaa Gulum Abbas pointed to the WTC and said, “Those towers are coming down.” Most details apparently remain sealed. For instance Glass will claim that his sealed sentencing document dated June 15, 2001, lists threats against the WTC and Americans. Florida State Senator Ron Klein, who had dealings with Glass before 9/11, later will say he is surprised it took so many months for the US to listen to Glass: “Shame on us.” Klein will recall getting a warning from Glass, though he cannot recall if it mentions the WTC specifically. He will say he was told US intelligence agencies would look into it. Senator Graham later will acknowledge that his office had contact with Glass before 9/11, and was told about a WTC attack: “I was concerned about that and a dozen other pieces of information which emanated from the summer of 2001.” However, Graham will say that he personally was unaware of Glass’s information until after 9/11. In October 2002, Glass will testify under oath before a private session of the 9/11 Congressional Inquiry, stating, “I told I have specific evidence, and I can document it.”
