HE'S DONE THE dON, NOW THE bULL:

An esteemed former federal judge himself, Gleeson, 66, entered the discourse around the Flynn case on Monday, when he and two other former Justice Department officials wrote in The Washington Post that among the steps US District Judge Emmet Sullivan could take would be to "appoint an independent attorney to act as a 'friend of the court,' ensuring a full, adversarial inquiry."

Saying the case "reeks of improper political influence," they wrote that "if prosecutors attempt to dismiss a well-founded prosecution for impermissible or corrupt reasons, the people would be ill-served if a court blindly approved their dismissal request. The independence of the court protects us all when executive-branch decisions smack of impropriety; it also protects the judiciary itself from becoming a party to corruption."

Now, according to Sullivan's order, Gleeson will articulate an argument against the Department of Justice's effort to end the prosecution and will weigh whether Flynn should face a perjury charge for contradictory statements he has given the court.

Former colleagues, contemporaries and friends of Gleeson's -- even some who have expressed sympathy for Flynn's position -- said they expect Gleeson's rigor, intellect and experience to be a welcome counterweight to the tumult of the case so far.
