Vladimir Putin takes a holiday in Siberia

Russian President Vladimir Putin has reacted to President Joe Biden calling him a “killer” by challenging Biden to take part in a conversation with him broadcast live online. Putin’s invitation seemed to amount to a challenge to Biden to a live televised debate, following a day of diplomatic uproar that began when Biden said he thought Putin was a “killer” in an interview with ABC News’ George Stephanopoulos. Russia recalled its ambassador to the United States in response to the remark.
