Biden says Putin is 'not going to scare us,' after Russian leader refers to using 'all available means'

President Joe Biden on Friday fired back after Russian President Vladimir Putin signed treaties to annex regions of Ukraine and said he would use "all available means" to protect them. "He's not going to scare us ... or intimidate us. Putin's actions are a sign he's struggling," said Biden, whose administration has rolled out new sanctions on Russia. The U.S. president also said recent Baltic Sea pipeline leaks were due to a "deliberate act of sabotage" that the country and its allies were investigating, while Russians are "pumping out disinformation."
