FBI agents seized documents related to potential criminal activity involving Hillary Clinton, the Clinton Foundation, and Uranium One from the home of a Department of Justice whistleblower, according to The Daily Caller.

The Daily Caller's Richard Pollock reported that the raid at the home of Dennis Nathan Cain took place on the morning of Nov. 19. Information about the raid comes from Cain's lawyer, Michael Socarras.

Socarras expressed outrage over the raid, saying Cain had already legally given the documents to congressional intelligence committees.

"The bureau raided my client to seize what he legally gave Congress about the Clinton Foundation and Uranium One," Socarras told The Daily Caller.

"For the bureau to show up at Mr. Cain's home suggesting that those same documents are stolen federal property, and then proceed to seize copies of the same documents after being told at the house door that he is a legally protected whistleblower who gave them to Congress, is an outrageous disregard of the law," he said.

What are these documents? According to The Daily Caller, some of the documents detail that federal officials neglected to investigate Hillary Clinton, the Clinton Foundation, and the Russian company that purchased Uranium One (Rosatom).

Other seized documents allegedly show that Robert Mueller, then the FBI director and now the special counsel investigating the Trump campaign, failed to investigate Rosatom and other Russian companies connected to Uranium One for potential criminal activity.

According to Socarras, Cain had already given those documents to the House and Senate Intelligence Committees by way of the DOJ Inspector General's office. He allegedly obtained them while working as a contractor for the FBI.

Did the FBI fully disclose what they were doing? Socarras told The Daily Caller that he finds it hard to believe the FBI was clear that they wanted to raid a protected whistleblower's home when they applied for a search warrant.

"I cannot believe the bureau informed the federal magistrate who approved the search warrant that they wanted to search the home of an FBI whistleblower to seize the information that he confidentially disclosed to the IG and Congress," Socarras said.

The raid, which lasted more than six hours and involved 16 agents, was approved by federal magistrate Stephanie A. Gallagher of the U.S. District Court in Baltimore on Nov. 15.

Socarras said the FBI has not reached out to him since the raid, and actually bypassed him to talk directly to Cain despite knowing who his lawyer was.
