As of now Ronald Reagan was the last to use his speech on April 22, 1981, observing "Days of Remembrance of Victims of the Holocaust." to acknowledge the killings. "Like the genocide of the Armenians before it, and the genocide of the Cambodians which followed it -- and like too many other such persecutions of too many other peoples -- the lessons of the Holocaust must never be forgotten," Reagan said.

On October 10, the Foreign Affairs Committee of the U.S. House of Representatives approved a resolution "says the killing of up to 1.5 million Armenians was genocide and that it should be acknowledged fully in U.S. policy toward Turkey, along with "the consequences of the failure to realize a just resolution.""
George W. Bush led the charge against this resolution stating that it would do serious harm to U.S. standings with Turkey.

President Obama, though he stated he would acknowledge the genocide back-peddled today and only stated "he had not changed his view from the campaign, even as he declined to state it, and added: "My interest remains the achievement of a full, frank and just acknowledgment of the facts."" THis happened even though he "strongly support passage of the Armenian Genocide Resolution (H.Res.106 and S.Res.106)" while he was Senator.
