Who is the current President of the United States as of 2023?

The correct answer is Joe Biden, who is serving as the President of the United States as of 2023. Joe Biden was inaugurated on January 20, 2021, after winning the presidential election held in November 2020. His administration focuses on various key issues, including the handling of the COVID-19 pandemic, infrastructure development, climate change initiatives, and social equity.

The other individuals mentioned have previously held the office of the President, but none are currently in that position as of 2023. Donald Trump served as the 45th president prior to Biden, Barack Obama was the 44th president, and George W. Bush served as the 43rd president. Each of these presidents has had significant impacts on America during their respective terms, but only Joe Biden is relevant to the question regarding the current presidency.
