Robert F. Kennedy Jr., President Trump’s pick to lead the Department of Health and Human Services, faced senators at his first confirmation hearing on Wednesday, before appearing before the Senate Committee on Health, Education, Labor and Pensions on Thursday.

Kennedy’s hearing was contentious, with Democrats pressing him on inflammatory and inaccurate statements he has made in the past on vaccines, COVID-19 and other topics. There was some hope that he might attract some Democratic support, but there was little indication that will be the case. RFK Jr. had tense exchanges with several Democrats on the panel.

The hearing before the Senate Finance Committee began at 10 a.m. ET and ended about 3.5 hours later. Here are some of the key moments from the hearing.
