The Iraq Study Group was a bipartisan panel created by Congress to recommend a better U.S. strategy in Iraq. The panel was headed by former Secretary of State James A. Baker III and Lee Hamilton, a former member of Congress who chaired the House Foreign Affairs Committee.
In December 2006, the group released its report, The Way Forward: A New Approach, which recommended a new U.S. strategy. The 142-page report focused on the future of Iraq and did not address whether Saddam wanted to restart a nuclear program. So we find Thompson's claim to be False.
It's possible that Thompson was referring to the Iraq Survey Group, a CIA panel that was formed to investigate whether there were weapons of mass destruction or the intent to produce WMDs in Saddam Hussein's Iraq. The report found that Saddam did not produce or possess any weapons of mass destruction for more than a decade before the U.S.-led invasion, but that he "aspired to develop a nuclear capability — in an incremental fashion, irrespective of international pressure and the resulting economic risks."
