Earlier on in the nomination hearing, Dr Sinha was warmly introduced by Republican Senator Lindsey Graham.
Dr Sinha has been friends with Mr Trump for over a decade and Mr Graham himself has known him for years, the senator said.
Mr Graham said that Singapore has a very “vibrant medical community, a lot of medical tourism, biotech, medical innovation”.
“All of this is right up his alley … He’ll be a great spokesperson for our country and Singapore, and he knows the region and the issues,” said Mr Graham.
Republican senator Pete Ricketts noted that he met with Singapore Prime Minister Lawrence Wong, Foreign Minister Vivian Balakrishnan and Defence Minister Chan Chun Sing at the Shangri-La dialogue earlier this year.
When asked what areas he would prioritise to strengthen the US-Singapore partnership and deepen cooperation as ambassador, Dr Sinha said: “As you know, I am a physician, a surgeon, so I have been a long-time bridge builder and I believe strongly in a person-to-person connection.”
“If confirmed, my first basis would be to go there and create a very good, strong relationship with Singapore government. And obviously, I will do my best to increase … I will deepen the defence security and economic ties with Singapore.”
Mr Ricketts said that Dr Sinha would make “a good connection with the foreign minister there” as Dr Balakrishnan is also a physician.
Dr Sinha said: “Actually, him and I, we have so many things in common. He went to his school and became an eye surgeon. I went to his school and became an orthopaedic surgeon.”
“His wife is a physician who became a neurologist. My wife is an anaesthesiologist. His kids are lawyers. Our kids are lawyers and doctors. So we have a strong connection already.”
In March, Trump named Dr Sinha as his nominee to be the country’s ambassador to Singapore.
In a post on Truth Social then, Mr Trump said: “Anji is a highly respected entrepreneur, with an incredible family.”
He added: “The United States’ relationship with Singapore is vital, and I have no doubt that Anji will strongly represent our nation’s interests and put America first.”
Dr Sinha is a surgeon on the East Coast specialising in orthopaedics and sports medicine.
The US State Department said he is an “accomplished entrepreneur, having built multiple thriving key-man practices with specialised teams across eight locations in New York, and has served as a senior surgical consultant in Florida”.
Dr Sinha is a graduate of MGM Medical School and Delhi University in India, with a Masters of Orthopaedic Surgery.
