The message came on Wednesday evening local time, after at least one distributor stated that it would replace the program "Jimmy Kimmel Live!" after the host's comments.
It was in Monday's broadcast that Kimmel hinted that Kirk's suspected murderer Tyler Robinson could be a Trump supporter.
The gang is desperately trying to portray the guy who killed Charlie Kirk as something other than one of them and is doing everything they can to win political points from it, said Kimmel.
Trump: Congratulations ABC
The 31-year-old debater Charlie Kirk was shot dead while speaking in front of a large crowd at Utah Valley University last week.
Kimmel has long used his daily talk show on the TV channel ABC to criticize and tease Trump. The President has in turn raised the tone against Kimmel and other comedians with demands that they be removed from the air.
"Congratulations to ABC for finally having the courage to do what needed to be done. Kimmel has ZERO talent", Trump writes on Truth Social after the message.
Aired for the first time in 2003
In the post, the President further writes that only "Jimmy and Seth" are left, where he refers to the talk show hosts Jimmy Fallon and Seth Meyers, whose programs are broadcast on the TV channel NBC.
"Do it NBC!!!", Trump urges.
This summer, the news came that the talk show "The Late Show", with host Stephen Colbert, will be laid to rest next year. The TV channel CBS claims that the closure is a "financial decision", while critics mean that the TV company has laid down for President Trump.
"Jimmy Kimmel Live!" was aired for the first time in 2003.
