Former White House strategist Steve Bannon has a theory on who wrote a bombshell anonymous "New York Times" article critical of President Trump.

FOX's Rachel Sutherland reports from Washington:

Steve Bannon believes the op-ed is a part of a broader conspiracy within the administration, telling 'The Ingraham Angle' on Fox News there's probably "six to a dozen people" in on it:

(Bannon) "I don't think there's any one author. I think there's somebody who drafted it. There are many voices in there."

Bannon, who left the White House last year, urged the Trump administration to find out who's responsible for the op-ed, which said administration officials had considered using the 25th Amendment to start the process of removing the President.
