WATCH: RFK Jr. swearing-in ceremony in Oval Office

President Donald Trump will take part in a swearing-in ceremony for Robert F. Kennedy Jr. as the Secretary of Health and Human Services on Thursday.

The Senate confirmed RFK Jr. on Thursday morning.

Republicans hold a 53-47 majority in the Senate and the 52-48 vote for President Trump's controversial nominee fell largely along those lines, with former majority leader Mitch McConnell – who had polio as a child – the only Republican to vote no.

Leading up to the confirmation, Kennedy appeared before the Finance Committee and the Health Committee. His confirmation was initially far from certain in the Senate after facing pointed questioning from both Republicans and Democrats on both committees.

Robert F. Kennedy Jr. is the son of Democratic icon Robert F. Kennedy, who was assassinated in 1968 during his own presidential campaign.

The 71-year-old, whose famous name and family tragedies have put him in the national spotlight since he was a child, has spent years airing his populist — and sometimes controversial — views in podcasts, TV interviews and speeches, building his own quixotic brand.

Health and Human Services has a broad reach across the lives of Americans, including inspecting the nation’s food, regulating medicines and overseeing research of diseases and cures. It provides health insurance for nearly half of the country — poor, disabled and older Americans, including via Medicare.

The agency oversees a $1.7-trillion budget.

I was so touched, to tears, when Bobby was speaking about how Trump was a man of his word and beyond. Bobby didn’t need anything in writing from Trump as his friends suggested, a handshake was Trump’s bond to get Bobby to the finish line. I pray God is with Bobby Kennedy to Make America Healthy Again. Not only Bobby’s prayers were answered, but ours were, too. We’ll have chemical free foods to keep us and our children healthy. God bless America, and God bless and keep President Trump and our new Secretary of HSS safe. 🙏🏻❤️🇺🇸

It's really sad how the Kennedy family and the dnc pretty much abandoned him... left him to fend for himself... until he and Shanahan had enough.

Trump you should give Shanahan a job too!

I waited so long for this moment, finally R F Kennedy Jr!!!!🤗🎊❤️
I have great hope that we’ll eat healthier; live healthier;and receive healthier care. Please help us seniors receive affordable health care, dental care. Please help the end of suppression of naturopathic doctors and treatments;
There are so many allergic reactions and health issues because of the chemicals in food and drugs. Waiting for total change in FDA and end of Obama care; which is a burden to doctors, nurses, medical staff and patients. Praying for great change in health care!!!!🙏🙏🙏
