Stephen Miller’s Rise to White House Chief of Staff Reenergizes RFK Jr.’s MAHA Movement

Health Secretary Robert F. Kennedy Jr. and his Make America Healthy Again allies see Miller’s appointment as a potential turning point in their fight over pesticides, vaccines and food policy, even as political setbacks and affordability concerns threaten the movement’s influence.

WASHINGTON | Stephen Miller’s elevation to White House chief of staff has given Health and Human Services Secretary Robert F. Kennedy Jr. and his Make America Healthy Again movement a renewed sense of political momentum, raising expectations that President Donald Trump’s administration could take a more aggressive approach to pesticides, food regulation and public health policy.

For Kennedy’s supporters, Miller’s appointment represents more than a change in White House leadership. It offers a potential opportunity to revive an ambitious health agenda that has encountered resistance from industry groups, competing administration priorities and a Republican Party increasingly focused on economic concerns.

“Next to me, Stephen Miller is the strongest MAHA supporter in the administration,” Kennedy wrote Friday on the social media platform X. “It’s time to unleash the Kraken.”

The declaration underscores the extraordinary expectations surrounding Miller, a longtime Trump adviser best known for shaping the president’s hard-line immigration policies.

But Miller’s new position also presents a significant political test: Can the White House advance Kennedy’s controversial health priorities without alienating business interests, medical organizations and voters more concerned about grocery prices than regulatory reform?
