Sadly, G. Gordon Liddy did not live to see the 20th anniversary of 9/11, as depicted in the hit 2005 comic book Liberality For All:
It is 2021, tomorrow is the 20th anniversary of 9/11. America is under oppression by ultra-liberal extremists which have yielded governing authority to the United Nations. It is up to an underground conservative group (known as F.O.I.L.) led by Sean Hannity, G. Gordon Liddy and Oliver North to thwart Ambassador Usama Bin Laden’s plans to nuke New York City.
The full synopsis is way goofier than I’d remembered.
