The Clinton-funded dossier was also used by the FBI to justify seeking a FISA surveillance (spy) warrant on the Trump campaign.

According to the FEC, Clinton and the DNC violated strict rules governing disclosure of expenditures on opposition research, when they paid opposition research firm Fusion GPS to contract with Steele and cook up propaganda against Trump.

A combined $1,024,407.97 was paid by the treasurers of the DNC and Clinton campaign to law firm Perkins Coie for Fusion GPS's information, and the party and campaign hid the reason, claiming it was for legal services, not opposition research.

Instead, the DNC's $849,407.97 and the Clinton campaign's $175,000 covered Fusion GPS's opposition research on the dossier, a basis for the so-called "Russia hoax" that dogged Trump's first term. -Washington Examiner
