Top Colorado Democrat Rebukes Kiros Over Refusal To Call Boulder Attack Antisemitic

Phil Weiser’s public criticism underscores deep party tensions over Israel messaging as Kiros moves into the general election.

Overview

  • Melat Kiros defeated 15-term Rep. Diana DeGette and became the Democratic nominee for Colorado’s 1st District in the primary held on Tuesday, June 30, 2026.
  • In a local 9News interview Kiros said she did not know the attacker’s intentions and declined to label the deadly Boulder firebombing as antisemitic, saying the motive was unclear.
  • Colorado Attorney General Phil Weiser publicly called the June 1, 2025 Boulder attack an antisemitic hate crime and said he would raise his concerns about Kiros’ language when they meet.
  • The dispute is anchored in the factual record that Mohamed Soliman carried out the June 1, 2025 firebombing at a pro‑Israel demonstration that killed 82‑year‑old Karen Diamond and that Soliman pleaded guilty and received a life sentence.
  • Kiros’ victory and her statements about Israel have drawn national progressive endorsements and sharp coverage across the political spectrum, which could shape Democratic messaging and voter outreach in the fall.
