The New York Post has an explosive report on the infamous “dossier” that tried to smear Donald Trump in order to swing the presidential election to Hillary Clinton. The source of the dossier is a Democratic Party opposition research firm called Fusion GPS:

The Senate Judiciary Committee earlier this month threatened to subpoena the firm, Fusion GPS, after it refused to answer questions and provide records to the panel identifying who financed the error-ridden dossier, which was circulated during the election and has sparked much of the Russia scandal now engulfing the White House.

Fusion GPS was on the payroll of an unidentified Democratic ally of Clinton when it hired a long-retired British spy to dig up dirt on Trump. In 2012, Democrats hired Fusion GPS to uncover dirt on GOP presidential nominee Mitt Romney. And in 2015, Democrat ally Planned Parenthood retained Fusion GPS to investigate pro-life activists protesting the abortion group.

No surprise there. What is shocking is the FBI’s apparent involvement in the effort to smear Trump with false rumors:

The FBI received a copy of the Democrat-funded dossier in August, during the heat of the campaign, and is said to have contracted in October to pay Steele $50,000 to help corroborate the dirt on Trump — a relationship that “raises substantial questions about the independence” of the bureau in investigating Trump, warned Senate Judiciary Chairman Chuck Grassley, R-Iowa.

It raises more questions than that. Why was the FBI meddling in a U.S. presidential election? Partisan interference in the election by public agencies like the FBI and major news sources like NBC are far more worrisome than anything Russians allegedly might do from afar.

The FBI, too, is trying to stiff Congress’s investigation into the fake dossier:

Senate investigators are demanding to see records of communications between Fusion GPS and the FBI and the Justice Department, including any contacts with former Attorney General Loretta Lynch, now under congressional investigation for possibly obstructing the Hillary Clinton email probe, and deputy FBI director Andrew McCabe, who is under investigation by the Senate and the Justice inspector general for failing to recuse himself despite financial and political connections to the Clinton campaign through his Democrat activist wife. Senate investigators have singled out McCabe as the FBI official who negotiated with Steele. Like Fusion GPS, the FBI has failed to cooperate with congressional investigators seeking documents.

It appears that the Democratic Party has successfully corrupted the FBI as well as the CIA.
