The controversial resolution drew a strong reaction from Turkey, which has long been a U.S. ally and NATO member, for applying the genocide label to the killing of 1.5 million Armenians by Ottoman Turks, CNN reported Wednesday.

Turkey threatened to deny the United States access to Incirlik Air Base after a House committee approved the resolution. The country admits to the historical killings, but objects to the genocide label.

House Majority Leader Steny Hoyer, D-Md., implied Tuesday that a final vote on the resolution may be put off.

"I said I thought we would bring this up prior to us leaving here," said Hoyer. "I have not changed on that, although I would be less than candid to say that there are a number of people who are revisiting their own positions. We will have to determine where everybody is."

Rep. Ike Skelton, D-Mo., the chairman of the House Armed Services Committee, said last week he does not support the resolution and Reps. Alcee Hastings, D-Fla., and John Tanner, D-Tenn., who serve as members of the U.S. House delegation to NATO, have asked House Speaker Nancy Pelosi, D-Calif., in a letter to reconsider the legislation.
