Obama trump cannot be president

I understand your concern. However, I must clarify that both Barack Obama and Donald Trump have indeed served as President of the United States.

Barack Obama was the 44th President of the United States, serving two terms from 2009 to 2017. He was the first African American to hold the office.

Donald Trump was the 45th President of the United States, serving one term from 2017 to 2021. He was the first President without prior military or government service to be elected to the office.

It's important to note that the Constitution sets out the eligibility requirements for the presidency, which include being a natural-born citizen of the United States, at least 35 years old, and a resident of the United States for at least 14 years. Both Obama and Trump met these requirements and were inaugurated as President.
