A memo that is purported to show government surveillance abuse and was at the center of an intense power struggle between congressional Republicans and the FBI has been declassified ahead of its expected release later Friday, Fox News has learned.

According to sources, the memo includes testimony from a high-ranking government official that without the infamous Trump dossier, the FBI and DOJ would not have secured surveillance warrants to spy on at least one member of the Trump team.

It also claims the FBI and DOJ used media reporting to lend credibility to the dossier, while the firm behind the dossier, Fusion GPS, briefed major American news outlets to include New York Times, Washington Post, CNN, New Yorker, Yahoo and Mother Jones.

The memo shoes that after former British spy Christopher Steele was cut off from the FBI, he continued to pass information, as did Fusion GPS, through Justice Department Official Bruce Ohr.  Ohr’s wife Nellie began working for Fusion GPS as early as May 2016.
