President Donald Trump and his administration have wasted little time in attempting to clean house across the federal government and get rid of career bureaucrats and officials who are not aligned with or will actively obstruct Trump's policy agenda.

That is especially true at the politicized FBI, and a top Bureau official who was placed in charge of the New York Field Office last year, James Dennehy, was reportedly forced to resign on Monday, according to The Hill.

Dennehy's ouster was not particularly surprising, given that he had already been outspoken in his opposition to some of Trump's initial moves and had even encouraged his colleagues to "dig in" along with him to resist the president's agenda.

Dennehy reveals his forced resignation

Multiple media outlets obtained copies of a letter Dennehy sent to his co-workers on Monday to announce his departure, in which he wrote, "Late Friday, I was informed that I needed to put my retirement papers in today, which I just did. I was not given a reason for this decision."

He apologized for not fulfilling his two-year term as the assistant director in charge of the FBI's New York Field Office, to which he'd just been promoted last September, and shared his "immense feeling of pride" in briefly leading that "office of professionals."

At multiple points in his message, Dennehy noted the "independence" of the FBI and how the agents and officials who work for the Bureau "will never bend, break, falter, or quit on your integrity" and "will not sacrifice what is right for anything or anyone."

"I've been told many times in my life, 'When you find yourself in a hole, sometimes it's best to quit digging,'" he concluded. "Screw that. I will never stop defending this joint. I'll just do it willingly and proudly from outside the wire."

Why was Dennehy forced to resign?

NBC News reported that, according to multiple unnamed sources, Dennehy had been given the option to voluntarily resign or be fired, of which he obviously chose the former over the latter.

As for his supposed ignorance of the reason why he was forced to resign, that is willful on his part, as it seems pretty clear to all why the Trump administration felt it necessary for him to go.

It was barely more than a month ago in late January that Dennehy, in response to an initial purge of senior officials at FBI headquarters in Washington D.C. and orders for him to provide a list of all FBI agents, employees, and officials who worked on cases involving the Jan. 6 Capitol riot of 2021, revealed that he would cause trouble for the new administration.

In a letter to his colleagues at that time, he expressed his defiance toward the new leadership in the White House and seemingly encouraged others to "dig in" and serve as internal resistance to President Trump's agenda.

Another likely reason for the decision for Dennehy to go, per NBC News, was his apparent opposition to the administration's efforts to drop the clearly politically motivated criminal charges filed last year against Democratic New York City Mayor Eric Adams, who only found himself facing trouble for years-old alleged crimes after he spoke out against then-President Joe Biden's decidedly lax immigration enforcement policies.

Did Dennehy withhold Epstein files from AG Bondi?

There is perhaps one other pertinent reason behind Dennehy's forced departure that earned a brief mention from CNN -- a potential lack of trust from Attorney General Pam Bondi following the debacle last week that was her rollout of supposedly newly declassified documents about the late convicted pedophile billionaire Jeffrey Epstein that turned out to mostly be information already known to the public through prior leaks and court filings.

Bondi accused the FBI New York Field Office, led by Dennehy, of deliberately sabotaging her by secretly withholding thousands of Epstein-related documents that should have been turned over to her office
