From this article:

Key points included in the article:

• Whistleblower's name is Dennis Nathan Cain

• He provided classified documents regarding the Clinton Foundation and Uranium One

• Information/documents were given to DOJ inspector general, House and Senate intel committtees

• Documents showed then FBI Director Mueller didn't investigate criminal misconduct related to Uranium One

• Whistleblower's lawyer Michael Socarras says information was provided following legal processes and that raid by FBI violated whistleblower protections

• physical transfer of information was to an inspector general investigator in proper classified material handling (double wrapped).

• The raid was permitted by a court order signed on Nov. 15 by federal magistrate Stephanie A. Gallagher in the U.S. District Court for Baltimore and obtained by TheDCNF

• 16 agents raided whistleblower's home on Nov 19th in Union Bridge, Maryland

• whistleblower is a former FBI contractor

• FBI basis for the raid was possession of stolen federal property

• FBI was notified the whistleblower has a lawyer but directly contacted him anyway, which is a violation

Additional thought:

• They didn't provide the date that the information was provided to the IG and Congress, only the date of the raid. Could have been disclosed a long time ago.
