Schiller is a close confidant of President Donald Trump and formerly served as his bodyguard and de facto gatekeeper. His title is now White House director of Oval Office operations.

The House investigation's interest in Schiller is the "latest indication that the investigations are touching Trump's inner circle," according to ABC News.

Notably, Schiller delivered the letter to the FBI informing James Comey of his termination as FBI director.
