Newly obtained records indicate health secretary lied about Samoa trip during Senate confirmation hearings last year

A senior Democratic senator is calling for a criminal investigation into the US health secretary, Robert F Kennedy Jr, following reporting by the Guardian that indicated he lied during Senate confirmation hearings last year.

Ron Wyden of Oregon said: “RFK’s platform is built on lies and grifts that leave a trail of dead children in their wake. There are consequences for lying to Congress.”

Representative Mike Collins has been dogged by associations to white nationalism and antisemitism

• US politics live – latest updates

The US senator for Georgia Jon Ossoff, a Democrat, has slammed a “disgraceful and disqualifying” report that a former staffer for his Trump-backed Republican challenger Mike Collins shared images online of a swastika and depicting himself in Ku Klux Klan robes.

It is the latest instance of someone in Collins’s orbit facing scrutiny over racist or white nationalist conduct. Ossoff called the report “stunning” and said it “should shock the conscience of every Georgian”.

Letters obtained by Guardian and AP contradict testimony that 2019 visit to Samoa had ‘nothing to do with vaccines’

Newly obtained documents indicate that the US health secretary, Robert F Kennedy Jr, lied during two congressional hearings last year, when he told lawmakers who held the key to his confirmation that a 2019 visit to Samoa had “nothing to do with vaccines”.

Letters obtained by the Guardian and the Associated Press contradict that testimony. In one he wrote to the Samoan prime minister before the trip, Kennedy explicitly said he wanted to study the measles, mumps and rubella (MMR) vaccine in the Pacific island nation. In it, he used the words “vaccine” or “vaccination” eight times.

It’s about ‘kitchen-table populism’: focusing on Americans’ day-to-day economic struggles

This year’s Democratic primaries look and sound a lot more populist than usual. Brian Poindexter, a union iron worker running on a “workers first” message, won a House primary outside Cleveland. Sherrod Brown is mounting a Senate comeback in Ohio on the same “rigged system” message that has allowed him to outshine other Democrats in Ohio. Troy Jackson, a fifth-generation logger who built his career fighting corporate landowners, is the Democratic Senate nominee in Maine. And Josh Turek, a self-described “prairie populist”, is on the Senate ballot in Iowa.

In fact, according to research we’ve conducted through the Center for Working-Class Politics (CWCP), more than 70% of 2026 Democratic candidates now rely on populist rhetoric in their campaigns, laying the blame for our broken system on rich elites of one kind or another.
