The Anti-Defamation League condemned Rep. Rashida Tlaib (D-Mich.) on Thursday for meeting with an activist last week who has called Israel a “terrorist entity” and who has a “delusional ISIS-like ideology,” in addition to praising U.S.-designated terrorist groups such as Hamas and Hezbollah.

“No matter your political persuasion, all leaders—and Americans—need to unequivocally speak out against anti-Semitism and hate,” posted ADL CEO Jonathan Greenblatt in a Twitter thread. “That especially goes for members of Congress.”

“Days ago, @RashidaTlaib was photographed at an event with Abbas Hamideh, a man who has praised terrorist groups Hamas & Hezbollah and equated Zionists with Nazis,” he added. “We ask her to clarify his attendance and denounce his anti-Semitism.”

The ADL published a dossier on Thursday about Hamideh and his anti-Israel background.

Tlaib defended on Tuesday her meeting with Hamideh. “Right wing media targeting me again rather than focusing on the President’s reckless government shutdown,” she tweeted. “Yes, I am Muslim and Palestinian. Get over it.”

The partial government shutdown has lasted 27 days as U.S. President Donald Trump has said he will not sign government funding legislation unless it includes at least $5.6 billion for a border wall with Mexico.
