During the crisis, Whitlam had alleged that Country Party Leader Anthony had close links to the US Central Intelligence Agency (CIA). Subsequently, it was alleged that Kerr acted on behalf of the United States government in procuring Whitlam's dismissal. The most common allegation is that the CIA influenced Kerr's decision to dismiss Whitlam. In 1966 Kerr had joined the Association for Cultural Freedom, a conservative group that was later revealed to have received CIA funding. Christopher Boyce, who was convicted for spying for the Soviet Union while an employee for a CIA contractor, claimed that the CIA wanted Whitlam removed from office because he threatened to close US military bases in Australia, including Pine Gap. Boyce said that Kerr was described by the CIA as "our man Kerr". Whitlam later wrote that Kerr did not need any encouragement from the CIA. However, he also said that in 1977 United States Deputy Secretary of State Warren Christopher made a special trip to Sydney to meet with him and told him, on behalf of US President Jimmy Carter, of his willingness to work with whatever government Australians elected, and that the US would never again interfere with Australia's democratic processes.
