Following a short break, Jimmy Kimmel returned to Live on Monday with a bang. He took aim at President Trump’s new tariffs that caused chaos in the market and the ongoing measles outbreak affecting children nationwide.

As the late night host put it on the show: “Stocks are down, measles are up.”

Kimmel pointed fingers at Secretary of Health and Human Services Robert F. Kennedy Jr. for the surge in measles cases. Kennedy, who recently shifted his stance on vaccines, is now being held accountable as the number of measles cases in the U.S. spikes to nearly 600.

In a humorous tone, Kimmel commented, “Who would have thought that appointing a vaccine skeptic as Secretary of Health, and dismissing the experts in charge of monitoring infectious diseases, would have a negative impact?”

He then pointed to the recent death of an eight-year-old girl in Texas who died from measles pulmonary failure, marking the second death of the year. According to reports, she had no underlying health conditions. Kennedy even made an appearance at her funeral service, but that wasn’t enough to impress Kimmel.

“Another child died of measles in Texas which is especially awful because that doesn’t have to happen,” Kimmel lamented. “We have a way to prevent this from happening.”

He continued, “RFK Jr actually took a break from working on his pecs to go to the funeral service, to say what, I don’t know. Oops? But we seem to be pedaling backwards in every area of American life.”

Kennedy has since advocated in favor of the vaccine as the number of cases continue to climb.

“The most effective way to prevent the spread of measles is the MMR vaccine,” he said in a post on X. He reported that there are “642 confirmed cases of measles across 22 states, 499 of those in Texas.”

Kennedy vowed to continue working with Texas Governot Abbott to offer resources through the CDC to ease the spread of measles.
