NBC Nightly News anchor Brian Williams delivered a commencement address at Elon University on May 25, 2013 and included a heartwarming message to his son, Doug. Father's Day is Sunday so we thought you may want to view this sometime this week.

Brian talked about how people have a limited amount of time on earth to accomplish their goals and be with their loved ones. He also spoke of his trip to Moore, Okla., which was recently devastated by a tornado. Brian Williams also talked about how he met a father whose 9-year-old son was killed by the storm.

Then, at the end of the 15-minute address, Williams addressed his son directly, saying how proud he was to be his father. Watch the touching video here and, Happy Fathers Day.
