What is the name of the current President of the United States?

The current President of the United States is Joe Biden. He took office on January 20, 2021, after winning the presidential election held in November 2020. As the head of the executive branch of the federal government, the President's primary responsibilities include enforcing laws, overseeing the federal administration, and representing the country in diplomatic matters. Joe Biden previously served as Vice President from 2009 to 2017 under Barack Obama, which provided him with extensive experience in governance and policy-making.

In contrast, Donald Trump served as President before Joe Biden, from 2017 to 2021, while Kamala Harris is the current Vice President, not the President. Barack Obama, who served from 2009 to 2017, was in office before Trump and is also not the current President. Thus, the answer accurately reflects the current political leadership in the United States as of your training data up to October 2023.
