The Germans listened to his claims and debriefed him starting in December 1999, continuing to September 2001. Although the Americans did not have "direct access" to Curveball, information collected by the BND debriefing team was later passed on in part to the Defense Intelligence Agency in the United States. As an incentive to keep supplying information to German intelligence, Curveball had been granted asylum, as he had applied earlier in 1999 and failed. He had enough money that he did not have to work. He gave many hours of testimony about Iraq's WMD program and in particular its mobile weapons laboratories. Despite CIA technicians and weapon experts finding major flaws and inconsistencies with the designs and systems he asserted the military was developing, this information made it to the American government and although there were wide doubts and questions about the claimed informant's reliability and background, assertions attributed to Curveball claiming that Iraq was creating biological agents in mobile weapons laboratories to elude inspectors appeared in more than 112 United States government reports between January 2000 and September 2001. His assertions eventually made it into United States Secretary of State Colin Powell's address on February 5, 2003 to the United Nations detailing Iraq's weapons programs.
