Dodd was a high Party official in the USA and told Catholics, following her return to the Church, that she had orchestrated, along with other Party members, the insertion of over 1,000 men into seminaries - with the mission to undermine Catholicism from within.
Those men came of age, and position, right at the time of the Council. She told listeners that they were men of real influence in the Church.
Her autobiography is available online.
As to her identification of those she alleged to have helped infiltrate the Church, I have no knowledge. Thus, evidence that would stand up in court may or may not be had.

The Vernona files and other KGB docuмents released following the collapse of the USSR may also be referenced if one is seriously looking into the matter.
