Among Sidney Powell's Distinctions

Both the Washington Post and New York Times have published profiles of Sidney Powell. The Post reports:

At the age of 23, Powell was hired as an assistant U.S. attorney in San Antonio, a distinction she has many times said made her then the youngest federal prosecutor in the country.

I don't doubt that she was the youngest AUSA in 1978, when she graduated from UNC-Chapel Hill and began her career in Texas, but she was not the youngest AUSA in history.

That was Roy Cohn, who graduated from Columbia law school at age 20 and had to wait until his next birthday to be admitted to the bar. Irving Saypol, U.S. attorney for the SDNY, hired him that day (Cohn was already working in the office as a clerk).
