Citing Attorney General William Barr as "a grave threat to the fair administration of justice," hundreds of former DOJ attorneys have signed an open letter calling for him to step down.

Here's an excerpt:

The Justice Manual — the DOJ’s rulebook for its lawyers — states that “the rule of law depends on the evenhanded administration of justice”; that the Department’s legal decisions “must be impartial and insulated from political influence”; and that the Department’s prosecutorial powers, in particular, must be “exercised free from partisan consideration.”

All DOJ lawyers are well-versed in these rules, regulations, and constitutional commands. They stand for the proposition that political interference in the conduct of a criminal prosecution is anathema to the Department’s core mission and to its sacred obligation to ensure equal justice under the law.

And yet, President Trump and Attorney General Barr have openly and repeatedly flouted this fundamental principle, most recently in connection with the sentencing of President Trump’s close associate, Roger Stone, who was convicted of serious crimes.

The Department has a long-standing practice in which political appointees set broad policies that line prosecutors apply to individual cases. That practice exists to animate the constitutional principles regarding the even-handed application of the law. Although there are times when political leadership appropriately weighs in on individual prosecutions, it is unheard of for the Department’s top leaders to overrule line prosecutors, who are following established policies, in order to give preferential treatment to a close associate of the President, as Attorney General Barr did in the Stone case. It is even more outrageous for the Attorney General to intervene as he did here — after the President publicly condemned the sentencing recommendation that line prosecutors had already filed in court.

Such behavior is a grave threat to the fair administration of justice. In this nation, we are all equal before the law. A person should not be given special treatment in a criminal prosecution because they are a close political ally of the President. Governments that use the enormous power of law enforcement to punish their enemies and reward their allies are not constitutional republics; they are autocracies.

Amen. They acknowledge that Barr isn't going anywhere, though and so encourage current DOJ employees to "be prepared to report future abuses to the Inspector General, the Office of Professional Responsibility, and Congress; to refuse to carry out directives that are inconsistent with their oaths of office; to withdraw from cases that involve such directives or other misconduct; and, if necessary, to resign and report publicly — in a manner consistent with professional ethics — to the American people the reasons for their resignation."

As I write, the number of signatories is up to 1143, with more signatures in the pipeline. Of course Barr isn't going to resign. But the real value in this letter is to invite whistleblowing and public disclosure of Barr's misconduct.
