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

The current President of the United States is Joe Biden. His administration began on January 20, 2021, after winning the 2020 presidential election. Joe Biden, a member of the Democratic Party, previously served as Vice President under Barack Obama from 2009 to 2017, which showcases his extensive experience in federal government. This context is essential for understanding his role and policies as president.

In contrast, the other names listed refer to individuals who have served as president in the past: George W. Bush served from 2001 to 2009, Barack Obama from 2009 to 2017, and Donald Trump from 2017 to 2021. Thus, while they were all presidents, they do not hold the current office, which is why Joe Biden is the correct answer.
