U.S. President Joe Biden's admninistration said on Monday he would veto a standalone bill backed by House of Representatives Republicans that would provide aid to Israel, as it backs a broader bill providing assistance to Ukraine and Israel and providing new funds for border security. "The Administration strongly encourages both chambers of the Congress to reject this political ploy and instead quickly send the bipartisan Emergency National Security Supplemental Appropriations Act to the President’s desk," the Office of Management and Budget said in a statement. Officials from the Democratic president's administration have been working for months with Senate Democrats and Republicans on legislation unveiled on Sunday combining billions of dollars in emergency aid for Ukraine, Israel and partners in the Indo-Pacific region, with an overhaul of U.S. immigration policy.
