CNN has banned a conservative commentator from appearing on the network again after he told a Muslim journalist, “I hope your pager doesn’t go off,” an apparent reference to the spate of exploding pagers in Lebanon that most recently killed members of the Hezbollah militant group. Group were killed month.

Ryan Girdusky made the comment during a heated debate with Mehdi Hasan, a prominent British-American broadcaster and outspoken critic of Israel’s war in Gaza, on “CNN Newsnight” with host Abby Phillip.

Guests discussed comedian Tony Hinchcliffe’s racist jokes that overshadowed former President Donald Trump’s rally at New York’s Madison Square Garden on Sunday and continued to make headlines two days later.

As the debate heated up, Girdusky and Hasan argued over whether the latter had been labeled an anti-Semite. “I am a supporter of the Palestinians, I am used to it,” Hasan said.

Girdusky replied, “Well, I hope your pager doesn’t go off.”

Hasan replied, “Did you just say I should die?” You just said I should be killed.”

When Phillip made the comment, Girdusky apologized and claimed he heard Hasan say he supported Hamas. After a commercial break, both Girdusky and Hasan left the panel.

“There is no room for racism or bigotry at CNN or on our show,” the network said in a statement shared by Phillip on social media. “Our goal is to promote thoughtful conversations and debates between people who have deeply different opinions, to discuss important issues and promote mutual understanding,” it said.

“But we will not allow guests to be humiliated or to cross the line of politeness. Ryan Girdusky will not be welcome back on our network.”
