A member of Congress Friday called on the State Department to stop doing business with Xe, the North Carolina-based security company formerly known as Blackwater Worldwide. Rep. Jan Schakowsky, D-Illinois, asked Secretary of State Hillary Clinton whether the State Department had just signed a new $20 million dollar contract with Xe for Iraq, saying she is “very concerned” that the State Department may be signing new security contracts with Xe, both in Iraq and Afghanistan.
