I went to the link and was unable to find any reference to “Rathergate,” his attempt to influence a presidential election by presenting forged documents as though they were legitimate.
There is one small reference to “Rathergate” in the wiki link in the “Killian Documents” section. Easy to miss but do a page search and you’ll see it.
