Moderate Democrats are fuming over New York Democratic Rep. Alexandria Ocasio-Cortez’s closed-door warning last week that Democrats who vote with Republicans are “putting themselves on a list” – a comment interpreted as a primary challenge threat.

Ocasio-Cortez has since downplayed her comments, made in the wake of 26 Democrats joining Republicans to vote for a provision requiring Immigration and Customs Enforcement to be notified if illegal immigrants attempt to purchase guns.

Still, some House Democrats aren’t happy with her talk of a “list.”

“I don’t think it’s productive,” Michigan Rep. Dan Kildee said Saturday on Fox News’ “Cavuto Live.”
