The Senate has approved sending $680 million more in aid to Sudan to help the hundreds of thousands of refugees in the Darfur region. So far the U.S. government has spent on Sudan a fraction of what it is spending in Iraq. The Center for American Progress estimates the total U.S. aid sent to the Darfur region so far this year — $175 million — is roughly the equivalent of what the U.S. spends each day in Iraq.
