A feud between Reps. Ilhan Omar and Lauren Boebert only appeared to escalate after the two congresswomen spoke on the phone Monday, with the call apparently ending with Omar hanging up on Boebert after the two demanded apologies from each other.

Boebert, a Colorado Republican, said in an Instagram video that she first reached out to Omar on Friday following widespread outrage over comments she made calling the Somali immigrant and Muslim Democrat from Minnesota part of the “Jihad Squad” and joked that she could be a terrorist.
