U.S President Joe Biden delivered his first State of the Union address with a main theme of how the U.S. will be responding to Russia’s invasion of Ukraine.

Russian strikes have been killing civilians and forces were massing near Ukraine’s capital Kyiv and Russian President Vladimir Putin showed no sign of backing down.

Biden also addressed the severe sanctions the U.S. and its allies have imposed on Russia for its invasion of Ukraine, saying they have made Russian President Vladimir Putin’s “$630 billion war fund worthless.”

Biden announced that the U.S. will be closing off its airspace to all Russian flights, “further isolating Russia and adding an additional squeeze on their economy.”

Pres. Biden: “Tonight, I say to the Russian oligarchs and the corrupt leaders who bilked billions of dollars off this violent regime: no more. I mean it!” https://t.co/SLfrkxjM7F #SOTU pic.twitter.com/tfoLwEh4ku
