The 71-year-old Kushner will also be the ambassador to Monaco. He was approved with the votes 51 against 45, according to news agencies.
Kushner's real estate company, which is primarily active in New York and New Jersey, was founded in 1985.
In 2005, he was convicted of tax offenses, witness tampering, and campaign finance violations and was sentenced to two years in prison by a federal court. This led to a form of business ban in several states, which was lifted when Donald Trump pardoned him in 2020.
Kushner's son Jared married Donald Trump's eldest daughter Ivanka in 2009. Jared Kushner was an advisor during Trump's first term, among other things, in matters related to the Middle East.
US President Donald Trump nominated Charles Kushner to the ambassador post shortly after the election victory last autumn. On social media, Trump has described him as a phenomenal businessman, philanthropist, and "dealmaker".
