Why do you think USAID of all groups was involved in election meddling? Their involvement in US foreign policy is usually along the lines of PR and sometimes being used as cover.
The entire point of USAID was to be a central clearinghouse for funding U.S. government pet projects so that the CIA/DoD/DoS stopped funding opposite sides against each other. Didn't always work (See the Middle East), but that's why it exists.
