G. Gordon Liddy, the former FBI official who helped orchestrate the 1972 break-in at the Watergate complex under orders from President Richard Nixon, has died at the age of 90.

Liddy died on Tuesday at his daughter’s home in Fairfax County, Virginia, according to the Washington Post, which said his son, Thomas P. Liddy, confirmed the death but did not comment on a cause other than to say it was not related to COVID-19.
