President Joe Biden gave an emotional tribute and paid his respects to slain U.S. Capitol Police Officer William “Billy” Evans.
PRESIDENT JOE BIDEN: My prayer for all of you is that a day will come when you have that memory and I said you smile before you bring a tear to your eyes. I promise you it's going to come. It just takes a while. It takes a while. But when it comes, you'll know because he's still with you. He's still in your heart. Your son, your husband, your brother, your dad was a hero. And he's part of you. It's in your blood. My prayer for you is that moment of the smile comes before the tear quicker and longer.
