Caroline Kennedy has sailed through a confirmation hearing on her way to becoming the US ambassador to Japan.
Ms Kennedy, 55, the only surviving child of President John Kennedy, told the Senate Foreign Relations Committee she would focus on trade and military ties if confirmed.
A lawyer by training, Ms Kennedy was an Obama supporter in 2008 and 2012, but the BBC reports she has largely shunned political life.
On Thursday, Ms Kennedy faced gentle questioning, with several senators on the committee saying she would be a great ambassador, all but assuring her confirmation to the post.
If confirmed, Ms Kennedy would become the third generation of her family to serve in the US diplomatic corps.
Her grandfather, Joseph Kennedy Sr, was ambassador to Britain, while her aunt, Jean Kennedy Smith, was ambassador to Ireland.
