House Speaker Kevin McCarthy says he had a "productive" call with Joe Biden on Sunday. The president has called him from Air Force One, the presidential plane, in which he was returning from Japan.

Biden's concern is that the most extreme Republicans are willing to cause the default of U.S. obligations in order to pass the political bill. "Now is the time for the other side to move from their extreme positions," Biden said in a press conference in Hiroshima, Japan, on Saturday.
