James Boasberg, the judge Donald Trump says should be impeached over his handling of court proceedings regarding Trump’s hardline immigration policy, is currently conducting a hearing in a lawsuit filed over “Signalgate.”

Trump complained about Boasberg earlier today, posting a long rant in which he called Boasberg’s assignment “disgraceful” and implied it was rigged against him.

“Boasberg, who is the Chief Judge of the DC District Court, seems to be grabbing the ‘Trump Cases’ all to himself, even though it is not supposed to happen that way,” Trump wrote, adding: “The good news is that it probably doesn’t matter, because it is virtually impossible for me to get an Honest Ruling in D.C. Our Nation’s Courts are broken, with New York and D.C. being the most preeminent of all in their Corruption and Radicalism. There must be an immediate investigation of this Rigged System, before it is too late!”

Boasberg has also “ordered the agencies who participated in the Signalgate chat to preserve all Signal messages between 11-15 March and to provide an update to the court about efforts to do so”.
