As of October 2023, who is the President of the United States?

The President of the United States, as of October 2023, is Joe Biden. He has been in office since January 20, 2021, when he succeeded Donald Trump after winning the 2020 presidential election. Biden, a member of the Democratic Party, previously served as Vice President under Barack Obama from 2009 to 2017. His presidency has focused on various issues, including economic recovery, healthcare, and climate change.

Barack Obama served as President from 2009 to 2017 and is no longer in office. Donald Trump was the President before Biden, serving from 2017 to 2021, and he has been a prominent figure in the Republican Party. Kamala Harris, while a significant figure, serving as Vice President alongside Biden, is not the President. Thus, Joe Biden is the only correct choice for the current President as of October 2023.
