While Pitt had been in Shimmerspace, an organization bent on world domination known as the ThinkTank had created Pitt clones - one of which was sent to steal some alien artifacts from a military installation. For this, the U.S. Army sent both troops and their best officer Captain Curtis to kill Pitt. They only succeeded in killing Captain Curtis and the US soldiers, and Pitt went to the White House where he killed Bill Clinton's double on the lawn. Pitt somehow found out about the ThinkTank being behind it all and went to the Crossbow Technologies building where he killed their leaders, the Guileys.
