Strongly suspect this letter was probably organized quickly since multiple very outspoken dems aren't on there. Probably prioritized getting out faster rather than getting people signing
I mean it's not like AOC was light about it despite not signing
“If the federal government can disappear a legal US permanent resident without reason or warrant, then they can disappear US citizens too,” she wrote in a separate post. “Anyone—left, right, or center—who has highlighted the importance of constitutional rights + free speech should be sounding the alarm now.”

EDIT: AOC also already signed a seperate letter to Noem & the acting ICE director along with other NY dems making this article grossly misleading by claiming she didn't sign on
