There's still the Southern District of New York

Donald Trump’s firing of the U.S. attorney for Manhattan [Preet Bharara] once rattled the president’s critics, who predicted the end of the office’s famously fierce independence.

What a difference a year makes.

On Tuesday, officials at the New York outpost squeezed guilty pleas out of Trump’s former lawyer, Michael Cohen. While admitting to crimes including campaign finance violations, Cohen said some of his actions had been directed by Trump. At a press conference minutes later, Deputy U.S. Attorney Robert Khuzami announced, “We are here, prosecutors are here, law enforcement is here, the Department of Justice is here.”

“We are a nation of laws and the essence of this case is justice, and that is an equal playing field for all persons in the eyes of the law,” Khuzami said. “And that is the lesson that Mr. Cohen learned today, and it is a very harsh one for him.”

“There’s a culture there that’s been there for a long time, and it persists through political winds. It’s strong,” said Samuel Buell, a former federal prosecutor who teaches at Duke University School of Law.

When Trump put forth Geoffrey Berman to succeed Bharara, Democratic lawmakers derided the president’s decision to meet with Berman before the nomination.

Berman’s appointment also raised questions for other reasons. He was a partner at Greenberg Traurig LLP, a law firm where his colleagues included Rudolph Giuliani.

Beyond that, one of Berman’s primary clients at the law firm was Deutsche Bank AG, the embattled German company that loaned some $300 million to Trump from 2012 to 2015.

There was plenty of reason to worry. But, so far, it looks like the SDNY attorneys are still willing to take on whatever comes their way.

Two weeks ago, the Manhattan office brought insider-trading charges against a Republican congressman who was among Trump’s earliest and staunchest supporters on Capitol Hill. Then on Tuesday, it prosecuted Cohen.

One way Berman has preserved independence is by relying on Khuzami, his hand-picked deputy.

[The Cohen investigation] burst into public view in April with a highly unusual raid of the lawyer’s home and offices. Berman recused himself from the matter.

And for that, I'm surprised Trump hasn't railed against Berman like he has Sessions. Perhaps it's only because he hasn't personally been called up in the New York attorney's bailiwick. Yet.
