WASHINGTON (CNN) -- Some Democrats appear to be wavering on a highly contentious House resolution labeling Turkey's treatment of Armenians in World War I as genocide. A KC-135 tanker lands at Incirlik Air Base in southern Turkey in 2003. Turkey, a longtime U.S. ally and NATO partner, was incensed by the resolution calling the killing of Armenians by Ottoman Turks genocide and threatened to block access to Incirlik Air Base after the resolution passed a House committee vote. The base, in southern Turkey near Syria, is a major resupply center for U.S. operations in Iraq and elsewhere in the Mideast and Asia.
