Bill Clinton (with my cousin at the airport in NY, my cousin works for the FAA)
Condoleeza Rice (brothers gf's dad worked for the CIA)
James Carvel (spoke at my school)
Rob Lowe (at Johnny Rockets in DC, this past march)

those are the most recent I can think of. I know there have been a few more here and there,
and countless US soccer players, in fact someone who played on my brothers team in highschool is now on the national team
