Evidence was often kept from the FISA court that allowed the FBI to spy on the Trump campaign and former adviser Carter Page for a full year.

In addition to the revelation of validation team warning, Helson was also forced to admit he never alerted the FISA judges that the FBI had a prior investigation into Danchenko as a possible spy for Russia back in 2008-10. Instead, the FBI falsely told the court it had no derogatory information on Danchenko.

In truth, the FBI had allegations that Danchenko tried to offer money to Americans he expected to go into the Obama administration if they would provide him classified information, Durham said. The prosecutor said that probe was improperly shut down when the FBI incorrectly concluded Danchenko had left the United States. In fact, he had not.
