Old news, but I haven't heard much of anything about Joseph Pientka, but it seems that Bruce Ohr would take the information from Christopher Steele and then sit with Joseph Pientka who then fed the information into the ranks of the FBI.
"After every meeting with Steele, Ohr would sit down for an interview with FBI Special Agent Joseph Pientka, who would fill out official FD-302 interview forms to pass on the information within the FBI.
Whatever Inspector General Michael E. Horowitz’s investigators discovered in their interviews with Pientka, they are keeping a very tight lid on it."
