Ronald Reagan, addressing U.N. on June 19, 1982:
I speak today as both a citizen of the United States and of the world. … My people have sent me here today to speak for them as citizens of the world, which they truly are, for we Americans are drawn from every nationality represented in this chamber today.
Newt Gingrich addressing GOP on June 8, 2009:
