Suppose Barack Obama (born August 4, 1961) is an American politician and attorney who served as the 44th President of the United States from 2009 to 2017. He was the first African American president of the United States. Obama was previously a U.S. senator from Illinois and a member of the Illinois State Senate before that.
Can we infer that "Barack Obama was never a U.S. senator"? Yes, no, or maybe?
