The BBC have a video of George Galloway's testimony in front of the US Senate subcommittee for homeland security and governmental affairs, I've got to admit that I'm not a big fan of Galloway but I found it quite extraordinary that they would make such a serious accusation against him with evidence that couldn't even be called flimsy with glaring factual errors and to do so without even asking him to defend himself. Well he's well able to defend himself and demolished their case against him, watch the video and judge for yourself.
While you're at it have a look at these documents about Donald Rumsfeld's meeting with Saddam. The documents show that during this period of renewed U.S. support for Saddam, he had invaded his neighbor (Iran), had long-range nuclear aspirations that would "probably" include "an eventual nuclear weapon capability," harbored known terrorists in Baghdad, abused the human rights of his citizens, and possessed and used chemical weapons on Iranians and his own people. The U.S. response was to renew ties, to provide intelligence and aid to ensure Iraq would not be defeated by Iran, and to send a high-level presidential envoy named Donald Rumsfeld to shake hands with Saddam (20 December 1983). All declassified US Government documents obtained by George Washington University under the freedom of information act.
