NY Times sums up the Kennedy v public health hearing:

Robert F. Kennedy Jr. faced a withering barrage of questioning from a Senate committee on his vaccine policy and his record as President Trump’s health secretary, responding at times with clear disdain for the senators, public health data and the Centers for Disease Control and Prevention, which he oversees.

That’s just great, isn’t it? He has disdain for senators, public health data, and the CDC. He has confidence and pride in…his own unaided hunches.

Appearing before the Senate Finance Committee on Thursday, Mr. Kennedy blamed the C.D.C. for the number of American deaths during the Covid-19 pandemic, and said he did not trust the data that showed vaccines saved millions of lives in the United States and elsewhere during the pandemic. Mr. Kennedy also falsely asserted that there were no cuts to Medicaid in President Trump’s domestic policy bill, and rejected bipartisan criticism that his actions were making it harder for people to obtain vaccines.

And where does he get all this? Nowhere. It just comes from his own brain, which is empty. Trump might as well have strolled into Lafayette Square and grabbed the first person he saw to be the federal health secretary.

A few snapshots, in reverse temporal order:

Kennedy has been remarkably salty and dismissive with the senators. As Senator Wyden, who was sharply critical of him from the start, made some closing remarks, Kennedy took out his phone, looked down at it, and began to scroll.

…

Kennedy disputed Susan Monarez’s account of her firing as C.D.C. director. “I told her that she had to resign because I asked her, ‘Are you a trustworthy person?’ And she said no,” he said. Kennedy has previously refused to discuss his interactions with Monarez, saying he would not talk about personnel matters. He said she was “lying” when she said he had fired her because she would not accede to his demands on vaccine policy.

…

Kennedy’s heated back and forth with Senator Maggie Hassan of New Hampshire just now was the most striking example yet of his disdain for members of the committee, and his disregard for Capitol protocol.

“This is crazy talk. You’re just making stuff up,” Kennedy said to Hassan as she accused him of reducing transparency around health data and limiting access to vaccines.

“Sometimes when you make an accusation, it’s kind of a confession, Mr. Kennedy,” the Democratic senator replied.

You in particular, Mr. Kennedy.
