Calling it "non-partisan" is a bit of a stretch (in terms of what most people consider that term to mean)

Calling something "non-partisan" is often used to convey the notion that it's an even split between both teams, and the findings/conclusions are part of a true bipartisan consensus.
Their
non-partisan committee consists of
Chair - the judge who presided over the Derek Chauvin trial
Vice Chair - an executive from the HRC
An immigration lawyer
Two Immigration Studies professors from the University of Minnesota
A sociology professor from U of M
The chair of the American-Somali Leadership committee
Two union leaders
An ACLU leader for Minnesota
...and one token retired Police Chief from the suburbs. (and before anyone gets bent out of shape, I don't mean token as in "he's black", I mean token in terms of "see, we have a law enforcement guy on the committee")
While it may be "non-partisan" strictly in a semantic sense that the ACLU person may identify as a Libertarian, and 1 or 2 of them may identify as "independent". It's stacked in favor of the left-leaning viewpoints on the subject.
By that standard, Trump's cabinet was "non-partisan", in that RFK Jr. and Tulsi Gabbard were democrats/independents, so that means it's a well balanced entity, right??
This committee is basically tailored to producing the "expert" conclusion of "Conservative actions on immigration = bad"
