As the crowd at Concord High School in New Hampshire anxiously waited to hear Democratic presidential candidate Bernie Sanders give his victory speech Tuesday night, the Vermont senator was warming up—on a basketball court.

Sanders celebrated his victory by shooting hoops with his sons and grandkids, according to Fox News.

Sanders has always had a soft spot for basketball, and he once went up against New York City professional star Connie Hawkins, according to The Guardian.

During a CNN Democratic town hall in January, Sanders said growing up he considered himself a “very good athlete.’’ His Brooklyn elementary school basketball team even won the borough championship, he said.
