John Brennan asks Chief Judge Altonaga to prevent forum shopping

Former CIA Director John Brennan is asking Chief Judge Altonaga to keep the government from "judge shopping" its case to Judge Cannon. The letter urges that any future litigation flow through the court’s normal, neutral processes, rather than what Brennan’s counsel colorfully describes as prosecutors trying to engineer judicial home-field advantage. Here's the AP article about it.  And here's the 16-page letter, which starts like this:

We write this letter to Your Honor in your capacity as Chief Judge of the United States District
Court for the Southern District of Florida (SDFL) on behalf of our client John Brennan, the former
Director of the Central Intelligence Agency. We have been formally advised by prosecutors of the
Office of the United States Attorney for the Southern District of Florida that Director Brennan is
a target of grand jury investigation NS 1840-020 in the Miami Division (24-06), which is
examining the circumstances surrounding the production of the 2017 Intelligence Community
Assessment about Russian efforts to interfere in the 2016 presidential election in the United States.
As explained below, it has become clear that irregular activity is taking place in connection with
that grand jury investigation, which is affecting our client's rights to fair and impartial treatment
by the criminal justice system. One example is the violation of grand jury secrecy rules, by which
information about the investigation is being leaked to the media (see below at pages 15-16).
Another example of irregular activity – which is even more troubling and potentially harmful to
our client's rights - relates to the government's apparent effort to manipulate grand jury and case
assignment procedures to ensure that this investigation and any resulting prosecution will be
overseen by a particular District Judge of its preference.

Given the corrosive effect of judge-shopping on the perceived fairness and impartiality of the
criminal justice system – particularly when conducted by a federal prosecutor – we wish to alert
the Court to the evidence underlying our concern. And, as counsel to the identified target of this
investigation who has legal standing to challenge questionable prosecutorial conduct in the
handling of the investigation¹ – we request that Your Honor carefully consider this evidence and the clear inference of prosecutorial judge-shopping as you exercise your supervisory authority over
the prosecution's handling of this grand jury investigation.² In short, we are seeking assurance
that any litigation arising out of this grand jury proceeding will be heard by a judge who is selected
by the court's neutral and impartial processes, not by the prosecution's self-interested maneuvering
contrary to the interests of justice.

This letter will proceed through the following lines of discussion: (I) an introduction describing
the current environment in which certain federal prosecutors are increasingly overreaching as a
result of overt political pressure, and in which federal courts are, therefore, more closely
scrutinizing prosecutorial conduct and decision making; (II) an overview of the historical
background ofthe ongoing grand jury investigation; (III) a description ofthe Justice Department's
repeated efforts to forum-shop this investigation among different federal districts, including the
Eastern District of Pennsylvania and the Eastern District of Virginia, before assigning it to
prosecutors in this District; (IV) a description ofthe circumstances demonstrating that the United
States Attorney in your district is also judge- shopping the matter by steering it toward a favored
judge - the onlyjudge – in the Fort Pierce Division; (V) a discussion ofthe case law that prohibits
and condemns such judge-shopping, especially when conducted by the prosecution in a criminal
matter; and (VI) our request that the Court scrutinize the government's conduct in the current grand
jury investigation to detect and head off any prosecutorial judge-shopping that may threaten both
the perceived legitimacy of this Court and the judicial system and the due process rights of our
client.
