Looking at the medical handler / secret service fellow, the name on his name tag is too short to be “Oladotun Okunola”. But it is not “Todd Madison” either (The Washington Post mentioned his name).
I believe it is Todd Madison. There are three lines of words on his badge. Todd on the top line, Madison on the second line, and there is a word or abbreviation on the third line, but that could just be his title.
