Having recently watched the excellent Peter Levenda presentation on the wandering Bishops, I was reminded of a little nugget I found on Corso, whilst I was researching my own little tome, which appears to have recently had "citation needed' added,
In 1964, Corso was assigned to Warren Commission member Senator Richard Russell, Jr. as an investigator into the assassination of John F. Kennedy. Corso's role was to deliberately fabricate the "legend" of Lee Harvey Oswald as a so-called Marxist and Communist sympathizer when in fact Oswald circulated within the Dallas based White Russian pro-Czarist and anti-communist community frequented by Baron George de Mohrenschildt, George Bouhe, Ilya Mamantov and Marina Oswald[citation needed].

As for Mr Chase, well, I listened to about the first half hour of him a while back on c2c, which was literally all the BS I felt I could stand from him.
