Can you tell me why Trump called Obama's birth certificate into question?
<|assistant|>
President Donald Trump called former President Barack Obama's birth certificate into question to cast doubt on his eligibility to serve as President of the United States. Trump made repeated claims in 2011 that Obama may not have been born in the United States, and therefore did not meet the requirements to be President under the US Constitution. He continued to question the authenticity of Obama's birth certificate even after the President released it in April 2011.
