The FBI’s Bad Intelligence - WSJ

The bureau relied on a suspected Russian agent for the information it used to obtain a secret surveillance warrant against former Trump adviser Carter Page.

Huh. I missed reading about this little nugget in other publications.

Department of Justice Inspector General Michael Horowitz last year revealed that former spook Christopher Steele relied on one primary “subsource” for most of his accusations against the Trump campaign. This subsource was later identified as Ukrainian-born Igor Danchenko, who worked as a research analyst from 2005 to 2010 at the Brookings Institution in Washington. The latest disclosures show that Mr. Danchenko was the subject of an FBI counterintelligence investigation from 2009 to 2011, based on concerns he was a Russian agent and “a threat to national security.”
