I definitely remember an interview with Montgomery and Larry Klayman in which Montgomery specifically states that he saw Donald Trump among the names of those spied on. I’ll try to dig it up later tonight.
Here is another story about Montgomery

“CIA and NSA contractor-turned-whistleblower Dennis Montgomery speaks out about the surveillance on President Donald Trump in an interview with his attorney Larry Klayman, the founder of Judicial Watch and Freedom Watch, on the premiere episode of the new talk radio program “Special Prosecutor with Larry Klayman.” The program, which debuted on Sunday, May 14, is carried by Radio America, an Arlington, Virginia-based network.”
There is a link to the actual interview at the webpage.
