As of my last update in January 2022, Joe Biden was serving as the 46th President of the United States. He assumed office on January 20, 2021. Prior to his presidency, Biden served as Vice President under President Barack Obama from 2009 to 2017. He has had a long career in politics, also serving as a U.S. Senator from Delaware for several decades. If there have been any significant developments or events involving Joe Biden since then, I wouldn't be aware of them.
