In January 2008, Guergis revealed that opposition leader Stéphane Dion would be traveling to Kandahar, Afghanistan, to visit a reconstruction project. This visit, along with similar visits to sensitive war-torn regions by Canadian politicians of all parties, along with other notable Canadians, was supposed to have been kept secret for Dion's protection. After his return to Canada, Dion angrily criticized Guergis' action, saying that she put him at risk of possibly being attacked by the Taliban. In a letter to Harper, Dion demanded Guergis' resignation or firing, saying that Guergis committed a "gross breach of Canadian security" that raised doubts about her fitness for Cabinet.
