Trump 2nd term updates: Trump excludes low-value shipments from looming tariffs

Trump said during his Cabinet meeting Wednesday that he spoke with Environmental Protection Agency Administrator Lee Zeldin, and "he thinks he's going to be cutting 65 or so percent of the people from environmental."

Sources close to the EPA had mixed reactions to that news.

One federal employee with direct knowledge of EPA staffing told ABC News they were not surprised after Trump's attempts to reduce the agency in his first term. Others, though, said they were stunned by Trump's statements on Wednesday.

One source close to matters at the EPA said "that would be insanity" and questioned whether the president said 65 or 6.5%. They also speculated whether Trump may have left a word out after "environmental."

ABC News has reached out to the EPA for additional details about the alleged cuts and what the 65% includes. The agency has not yet responded.

"It's different, like, if the FAA doesn't fulfill its mission, you might see a plane crash tomorrow," the source said. "If EPA doesn't fulfill its mission, you might very well see actually like a devastating chemical leak within the next couple of weeks, but you'll almost certainly see a devastating cancer cluster in the next couple years or decades."

Trump held the first Cabinet meeting of his second term on Wednesday and in the room, and at times taking center stage, was Elon Musk.

For little more than an hour, Trump sought to tout his administration's work so far and fielded questions on everything from the status of Musk's efforts to force federal firings to negotiations to end Russia's invasion of Ukraine.

ABC News' Chief White House Correspondent Mary Bruce asked Trump about his interest in doing another round of emails demanding federal workers' accomplishments and what the requirements would be.

"I think Elon wants to, and I think it's a good idea because, you know, those people, as I said before, they're on the bubble," he responded, emphasizing his desire to find out if workers exist.

"And it's possible that a lot of those people will be actually fired. And if that happened, that's OK, because that's what we're trying to do," Trump said. "This country has gotten bloated and fat and disgusting and incompetently run."

Department of Health and Human Services Secretary Robert Kennedy Jr., who has advocated for anti-vaccination policies, was asked about the death of an unvaccinated child in Texas who contracted measles.

Kennedy said the agency is monitoring the reports of the outbreak in Texas, but appeared to downplay the situation.

"There have been four measles outbreaks this year in this country, last there that was 16, so it's not unusual to have measles outbreaks every year," he said.

This child's death marks the first measles death in the U.S. in a decade.

The CDC currently recommends people receive two vaccine doses, the first at ages 12 to 15 months and the second between 4 and 6 years old. One dose is 93% effective, and two doses are 97% effective. Most vaccinated adults don't need a booster.

Measles was declared eliminated from the U.S. in 2000 because of the highly effective vaccination program, according to the CDC. However, vaccination rates have been lagging in recent years.
