Trump admin live updates: White House drops NASA nominee with Musk ties

National Economic Adviser Kevin Hassett and White House Senior Counselor for Trade Peter Navarro spoke to reporters at the White House following a federal appeals court temporarily delaying Wednesday's court order that blocked Trump’s tariffs.

Pressed by ABC News’ Rachel Scott if all the back and forth on the legal challenges against the tariffs undermines negotiations, Hassett said, "No."

"Because the bottom line is that we are very, very confident that we're going to get this positive result, and we're even more confident that we're going to win at the end," he said.

As small businesses and the markets watch the pendulum swing of on-and-off tariffs, Scott asked Navarro if the administration will implement tariffs regardless of the circumstances.

“I think that's a fair assessment,” Navarro said.

While Elon Musk is stepping away from the White House, a senior administration official says he will continue to serve as an unofficial adviser to the president and could potentially attend White House meetings in the future.

While officials at the White House insist Musk and Trump left on good terms, it's notable the president hasn't said a word about Musk's departure, especially after his outspoken comments about the president's agenda and policy.

Senior White House officials were frustrated by Musk's comments regarding what Trump calls his “big, beautiful bill,” which came a day before Musk announced he would be officially leaving the administration, sources familiar with the situation tell ABC News.

Multiple senior DOGE officials are in the process of leaving the Trump administration as Elon Musk officially steps away, sources told ABC News.

Among them is James Burnham, DOGE’s top attorney, and Steve Davis, a longtime Musk lieutenant at his private companies. Both are in the process of offboarding from their role as special government employees, a White House official confirmed to ABC News.

Katie Miller, a special government employee who had served as a senior adviser and spokesperson for DOGE, is also leaving the administration and will work with Musk, sources said.

Burnham was a key attorney working closely with Musk and DOGE on the team's legal strategy. Davis served as one of Musk’s most senior advisers at DOGE -- and was viewed as running day-to-day operations – and worked across multiple federal agencies during his tenure.

Sources told ABC News other special government employees who worked with DOGE are also planning to be offboarded.

Special government employees are limited to 130 days of service. Friday will be 130 days since Inauguration Day, but it's unclear how each SGE counts their days worked.

A reporter asked White House press secretary Karoline Leavitt about a NOTUS article that found the Health and Human Services "Make America Healthy Again" report cited nonexistent medical studies and misrepresented others.

"I understand there were some formatting issues with the MAHA report that are being addressed in the report will be updated," she responded adding that the administration had confidence in Secretary Robert F. Kennedy Jr.

Leavitt could not provide more details about HHS's research or if AI was used in the report.

RFK JR., who has no formal medical training, has promoted unsubstantiated health information for years, particularly when it comes to vaccines.
