John McCain has been critical of China for its willingness to do business in Sudan. "China needs Sudan's oil," he has said. "The politics of oil impede the global progress of our values, and restrains governments from acting on the most basic impulses of human decency."

Turns out it's not just China that ignores Sudan's humanitarian atrocities in order to make a profit.

Cindy McCain, whose husband has been a critic of the violence in Sudan, sold off more than $2 million in mutual funds whose holdings include companies that do business in the African nation.

The sale on Wednesday came after The Associated Press questioned the investments in light of calls by John McCain, the likely Republican presidential nominee, for international financial sanctions against the Sudanese leadership.
