Joe Biden, the 46th President of the United States, has led an extremely eventful life. In 1972, Biden became a seven-term U.S. Senator from Delaware, serving 37 years in the Senate and casting more than 12,000 votes. He then served eight years as 47th U.S. Vice President under U.S. President Barack Obama. Along the way, he overcame personal tragedy, life threatening illness, and career setbacks to become a foreign policy expert and one of the most respected legislators in the United States.
