Biden in Delaware as Putin raises nuclear alert status

President Biden remains at his private home in Delaware as the Russian invasion of Ukraine continues to escalate.

Russian President Vladimir Putin raised the alert status for his nuclear forces to "special regime of combat duty" as Russia and Ukraine battle for the fourth day. 

Putin ordered the Russian defense minister and the chief of the military's General Staff to put the nuclear deterrent forces in a "special regime of combat duty." The move signals tensions could boil over into a nuclear war.

At the same time, Biden remains at his private residence in Delaware and media communications with the commander-in-chief have slowed to a crawl.

Putin warned last week that countries who interfere with his invasion of Ukraine will face "consequences you have never seen."
