The Justice Department is investigating a Brooklyn coffee shop that banned Rep. Dan Goldman over his support for Israel, as tensions over the Middle East fuel a rival’s surging bid to unseat him in Tuesday’s New York Democratic primary.

Poetica Coffee, a local chain, posted a photo of Goldman at its Williamsburg branch on Instagram with a caption saying that it did not serve “racists, fascists, homophobes, genocide enablers or anyone in between.”

Poetica added that Goldman would have been turned away if the staff had immediately recognized him. The shop said it had refunded Goldman his money, which was “probably coming from AIPAC.”
