I don't know how he made it thru Sat's speech. I would have needed a sedative.
He almost didn't. I noticed that he was blinking alot. A trick one uses when tears well up that you don't want streaming down your face. At the end, I thought I detected a tear on his right (viewer's left) cheek. At the end, when he said "May God bless the grieving families, and may God continue to bless America." his voice cracked on the second "God". He has such a look of sadness on his face...not a contrived, put on look, but a deep, hurting sadness.
