When Jimmy Kimmel took a swipe at Donald Trump on live television, nobody expected the former president to let it slide. Within hours, Trump issued one of his sharpest public rebukes yet—aimed directly at Kimmel, ABC, and what he called their “never-ending fake news circus.”

It all began after Kimmel mocked Trump’s recent comments to a reporter, where Trump was heard telling them to “be quiet, piggy.” The clip went viral, and Kimmel wasted no time turning it into a punchline on his show. But Trump wasn’t laughing.

A source close to the former president said Trump was “furious” and felt ABC was intentionally trying to humiliate him. In a message released shortly after the broadcast, Trump slammed Kimmel as “a failing comedian desperately clinging to relevance” and accused ABC of being “nothing but a propaganda arm for the radical left.”

According to the statement, Trump insisted he never cared about late-night comedians’ opinions, but that Kimmel had crossed a line by “twisting real events into smear campaigns.” He also claimed ABC was losing viewers because “Americans are tired of being force-fed lies disguised as jokes.”

Kimmel, for his part, hasn’t backed down. Sources say he is preparing an even more biting follow-up monologue, and ABC executives are reportedly bracing for another wave of political backlash.

One thing is certain: the long-running feud between Trump and late-night television isn’t cooling off anytime soon—and this latest clash may be one of their most explosive yet.
