Congressman Adam Schiff claimed on Sunday that the official who sits atop the intelligence community is rejecting a subpoena to turn over a whistleblower complaint in order to protect an even higher-ranking official, possibly a top administration official or even President Trump.

“According to the director of national intelligence (DNI), the reason he’s not acting to provide it, even though the statute mandates that he do so, is because he is being instructed not to. This involved a higher authority, someone above the DNI,” Schiff, who is chairman of the House Intelligence Committee, said in an interview with CBS News’ “Face the Nation.”
