Mr. Biden is expected to announce the symbolic designation on Saturday, the 106th anniversary of the beginning of what historians call a years long and systematic death march that the predecessors of modern Turkey started during World War I. He would be the first sitting American president to do so, although Ronald Reagan made a glancing reference to the Armenian genocide in a 1981 written statement about the Holocaust, and both the House and the Senate approved measures in 2019 to make its recognition a formal matter of U.S. foreign policy.
At least 29 other countries have taken similar steps — mostly in Europe and the Americas, but also Russia and Syria, Turkey’s political adversaries.
A U.S. official with knowledge of the administration’s discussions said Mr. Biden had decided to issue the declaration, and others across the government and in foreign embassies said it was widely expected.
In a statement 107 U.S. House members, in a bipartisan letter, ask President Joe Biden to “clearly and directly recognize the Armenian Genocide” in April 24 statement.
