Countries visited by Carter during his presidency
Carter made twelve international trips to twenty-five countries during his presidency.[256] Carter was the first president to make a state visit to Sub-Saharan Africa when he went to Nigeria in 1978.[204] His travel also included trips to Europe, Asia, and Latin America. He made several trips to the Middle East to broker peace negotiations. His visit to Iran from December 31, 1977, to January 1, 1978, took place less than a year before the overthrow of Shah Mohammad Reza Pahlavi.[257]

Allegations and investigations
The September 21, 1977, resignation of Bert Lance, who served as director of the office of management and budget in the Carter administration, came amid allegations of improper banking activities prior to his tenure and was an embarrassment to Carter.
