President Donald Trump's longtime bodyguard Keith Schiller, who now serves as the director of Oval Office operations, is looking to resign from his White House post by October.

CNN reported Friday that Schiller has told people his decision to leave the White House is based on financial reasons. He makes $165,000 working for the government, a significant decrease from his annual salary of what CNN reported was $294,000 when he worked as Trump's head of security before he was granted Secret Service protection during his campaign.

The network did report, however, that Schiller is frustrated with some of the new rules White House Chief of Staff John Kelly has put in place regarding access to Trump. Schiller reportedly has to call the White House switchboard when he wants to speak with Trump on the phone.

Schiller was a fixture on Trump's presidential campaign and traveled with him everywhere he went. He was spotted racing to the stage during a rally in Ohio last year when a spectator at the event jumped over the barriers.

Now that Trump is president, Schiller is often seen next to or near him during events.

When Trump fired FBI Director James Comey in May, he dispatched Schiller with a letter detailing the firing to the FBI's Washington, D.C. headquarters. Comey was out of town that day and learned about his fate via a news report.
