At a contentious hearing with Robert F. Kennedy Jr., the health secretary, Republicans who voted to confirm him were among his critics.

A three-hour hearing before the Senate Finance Committee revealed that the health secretary was on uncertain ground even with some Republicans who voted to confirm him.

Threatened by the president with political retribution, Republicans agreed to defund public broadcasting, imperiling a lifeline of communication in rural Alaska.

Since Congress approved President Trump’s request to claw back $1.1 billion in funding for public broadcasting, local stations in rural areas are at risk of going dark. Megan Mineiro, a congressional reporter for The New York Times, went to rural Alaska to see how the cuts affect one radio station and a town that relies on it.
