NEW LONDON, Conn. (AP) - President Joe Biden is scheduled to deliver the keynote address during this month's graduation ceremonies at the U.S. Coast Guard Academy. The address, scheduled for May 19, will be the second time Biden has addressed a graduating class at the academy. He also served as the keynote speaker in 2013 while serving as vice president. This will be Biden's first commencement address to a military service academy and his first official visit to Connecticut as president. Lyndon Johnson was the first president to speak at a Coast Guard graduation, addressing cadets in 1964.
