A top FBI official admitted to Congressional investigators last year that the agency had contacts within the Trump campaign as part of operation "Crossfire Hurricane," which sounds a lot like FBI "informant" Stefan Halper - a former Oxford University professor who was paid over $1 million by the Obama Department of Defense between 2012 and 2018, with nearly half of it surrounding the 2016 US election.
According to portions of transcripts published on Tuesday by the Epoch Times of a Aug. 31, 2018 deposition by Trisha Anderson, the FBI relied on sources who "already had campaign contacts" in order to surveil the Trump team.
"To my knowledge, the FBI did not place anybody within a campaign but, rather, relied upon its network of sources, some of whom already had campaign contacts, including the source that has been discussed in the media at some length beyond Christopher Steele," said Anderson - who was the #2 attorney at the FBI's Office of General Counsel, and had extensive involvement with the Trump counterintelligence investigation.
Halper is reportedly a longtime CIA and FBI informant, and has been involved in US politics at the highest levels for decades, becoming George H.W. Bush's National Director for Policy Development during his presidential campaign. After Bush lost to Reagan, Halper worked as Reagan's Deputy Assistant Secretary of State - where he served under three different Secretaries.
He then became a senior advisor to the Department of Defense and DOJ between 1984 and 2001. Halper's former father-in-law was Ray Cline, former Deputy Director of the CIA. He also allegedly spied on the Carter administration - collecting information on foreign policy (an account disputed by Ray Cline).
