This does appear to be the personal account for Magisterial District Judge Ron Arnoni, whose district covers Bethel Park and Upper St. Clair, I believe. Back in 2019 it retweeted someone tagging him with a photo while they waited to hang out with Guy Reschenthaler.

It’s probably too vague/dog-whistle-like to spur a whole judicial conduct investigation, but I’d wonder if publicly tweeting stuff like this (and insults at Alec Baldwin/Rob Reiner, for some reason) is just the tip of the iceberg for folks who are actually in his courtroom. I know he had some accusations of trying to make back room deals to smooth his path to a full term five years ago… but that never turned into an official investigation or case.
