Pompeo's decision to speak at the convention was controversial because it's been seen as breaking with traditional norms. ABC News recently pointed out that no sitting Secretary of State had spoken at a party convention since at least 1976. So I did a little digging, and it turns out the last time a secretary of state spoke at a convention was in 1972, when William Pierce Rogers gave a tribute to Dwight Eisenhower, who had died in 1969.
