A New York coffee shop is in the news after it publicly shamed a pro-Israel congressman, and now faces legal threats and a federal probe.

• Brooklyn's Poetica Coffee called out Rep. Dan Goldman online after he bought a coffee, saying it doesn't serve "genocide enablers" and would have turned him away.
• Goldman, a strong Israel backer, just lost his Democratic primary to Brad Lander, who also calls Gaza a genocide but criticized the shop's tactic.
• Alan Dershowitz wants the Justice Department to shut the shop down and says he'll try to sue, claiming the snub is religious discrimination.
• The DOJ's civil rights division is reportedly opening an investigation into the incident.
• Polls show the backdrop: most Democrats now view Israel negatively, and Americans for the first time sympathize more with Palestinians.

Outlook: Expect more legal threats and federal pressure, but a discrimination case looks weak since refusing service over political views is not banned.
