Trump's main point of contention was that the FBI failed to follow protocol in order to obtain the warrant against his campaign.
Following a report on a chain of emails between FBI officials regarding FISA applications for a Trump associate that may contain "the most damning evidence to date of potential abuses of the Foreign Intelligence Surveillance Act (FISA)," President Trump brought up alleged FISA abuse in a series of tweets late Thursday.
On Wednesday, The Hill's John Solomon reported on emails recently requested for declassification by House Intelligence Committee Chair Devin Nunes (R-CA) that sources say could prove to be the smoking gun on FISA abuse by high-ranking FBI officials under Obama.
"The email exchanges included then-FBI Director James Comey, key FBI investigators in the Russia probe and lawyers in the DOJ’s national security division, and they occurred in early to mid-October, before the FBI successfully secured a FISA warrant to spy on Trump campaign adviser Carter Page," Solomon reports. "The email exchanges show the FBI was aware — before it secured the now-infamous warrant — that there were intelligence community concerns about the reliability of the main evidence used to support it: the Christopher Steele dossier. The exchanges also indicate FBI officials were aware that Steele, the former MI6 British intelligence operative then working as a confidential human source for the bureau, had contacts with news media reporters before the FISA warrant was secured."
Solomon's report has gained traction, including with Fox News, with Sean Hannity in particular promoting the report and inviting Solomon on his radio show Thursday to discuss the story.
Trish_Regan: “Did the FBI follow protocol to obtain the FISA warrant? I don’t think so. The Dossier was opposition research funded by opponents. Don’t use Government resources to take down political foes. Weaponizing Government for gain.” Is this really America? Witch Hunt!— Donald J. Trump (@realDonaldTrump) December 7, 2018
....Foundation be listed at the top of the Report? Will the scathing document written about Lyin’ James Comey, by the man in charge of the case, Rod Rosenstein (who also signed the FISA Warrant), be a big part of the Report? Isn’t Rod therefore totally conflicted? Will all of....— Donald J. Trump (@realDonaldTrump) December 7, 2018
...the lying and leaking by the people doing the Report, & also Bruce Ohr (and his lovely wife Molly), Comey, Brennan, Clapper, & all of the many fired people of the FBI, be listed in the Report? Will the corruption within the DNC & Clinton Campaign be exposed?..And so much more!— Donald J. Trump (@realDonaldTrump) December 7, 2018
