Biden says U.S. would ‘respond’ to Russia if Putin uses chemical or biological weapons

President Joe Biden said Thursday that NATO would respond “in kind” if Russia uses weapons of mass destruction in Ukraine.

“We will respond if he uses it,” Biden said, referring to Russian President Vladimir Putin. “The nature of the response depends on the nature of the use.”

The president spoke after a marathon of summit meetings with the European Union, G-7 partners and NATO allies.

Biden also said he would support an effort to expel Russia from the G-20 group of economies.
