Jimmy Kimmel’s television future hung in the balance Thursday after ABC suspended his late-night show following the host’s comments about Charlie Kirk’s killing, which prompted dozens of stations to say they would not air the show, a move that was cheered on by a top federal regulator.

The veteran late-night comic made several remarks on Monday and Tuesday about the reaction to the conservative activist’s assassination, including saying that “many in MAGA land are working very hard to capitalize on" the fatal shooting. He said Trump's political supporters were trying to characterize the man charged in the attack “as anything other than one of them.”

ABC, which has aired “Jimmy Kimmel Live!” since 2003, moved swiftly after Nexstar Communications Group said it would pull the show starting Wednesday. Kimmel’s comments about Kirk’s death were “offensive and insensitive at a critical time in our national political discourse,” said Andrew Alford, president of Nexstar’s broadcasting division. Nexstar operates 28 ABC affiliates.

Another company that owns 38 local television stations, Sinclair Broadcast Group, called on Kimmel to apologize to Kirk’s family and make a “meaningful personal donation” to the activist’s political organization, Turning Point USA. Sinclair says its ABC stations will air a tribute to Kirk on Friday in Kimmel’s time slot.
