After returning from the G7 summit in Japan, Biden will meet Republican House Speaker Kevin McCarthy at the White House, with a warning that the government could run out of cash as soon as June.

Biden insisted he would not give in to demands for spending cuts, saying they were "frankly unacceptable". "It's time for the other side to move from their extreme positions," he said.
McCarthy said his position remained unchanged, tweeting: "Washington cannot continue to spend money we do not have at the expense of children and grandchildren." However, after speaking to Biden, he told reporters: "I believe it was a productive phone call."
