(You might be looking for George W. Bush. This is his father.)

The following exchange took place at the Chicago airport between Robert I. Sherman of American Atheist Press and George Bush, on August 27, 1987. Sherman is a fully accredited reporter, and was present by invitation as a member of the press corps. The Republican presidential nominee was there to announce federal disaster relief for Illinois. The discussion turned to the presidential primary:
RS: "What will you do to win the votes of Americans who are atheists?"
GB: "I guess I'm pretty weak in the atheist community. Faith in God is important to me."
RS: "Surely you recognize the equal citizenship and patriotism of Americans who are atheists?"
GB: "No, I don't know that atheists should be considered as citizens, nor should they be considered patriots. This is one nation under God."
RS: "Do you support as a sound constitutional principle the separation of state and church?"
GB: "Yes, I support the separation of church and state. I'm just not very high on atheists."

UPI reported on May 8, 1989, that various atheist organizations were still angry over the remarks.

The exchange appeared in the Boulder Daily Camera on Monday February 27, 1989. It can also be found in "Free Inquiry" magazine, Fall 1988 issue, Volume 8, Number 4, page 16.

On October 29, 1988, Mr. Sherman had a confrontation with Ed Murnane, co-chairman of the Bush-Quayle '88 Illinois campaign. This concerned a lawsuit Mr. Sherman had filed to stop the Community Consolidated School District 21 (Chicago, Illinois) from forcing his first-grade atheist son to pledge allegiance to the flag of the United States as "one nation under God" (Bush's phrase). The following conversation took place:
RS: "American Atheists filed the Pledge of Allegiance lawsuit yesterday. Does the Bush campaign have an official response to this filing?"
EM: "It's bullshit."
RS: "What is bullshit?"
EM: "Everything that American Atheists does, Rob, is bullshit."
RS: "Thank you for telling me what the official position of the Bush campaign is on this issue."
EM: "You're welcome."

After Bush's election, American Atheists wrote to Bush asking him to retract his statement. On February 21, 1989, C. Boyden Gray, Counsel to the President, replied on White House stationery that Bush substantively stood by his original statement, and wrote:
"As you are aware, the President is a religious man who neither supports atheism nor believes that atheism should be unnecessarily encouraged or supported by the government."
