Caroline Kennedy, the daughter of former president John F. Kennedy, is being vetted as the United States' next ambassador to Japan, CNN reported Monday.  

Kennedy would replace John Roos, who was appointed to the post in 2009, and would become the first woman to represent the United States in Tokyo.

White House press secretary Jay Carney refused to answer questions on Kennedy's potential nomination and her qualifications as an ambassador.

"I have no personnel announcements to make, and I have seen no reporting that sources supposed personnel decisions to anyone on the record from the White House to the administration," Carney said. "So I think I'll leave it at that."

Kennedy was a key fundraiser for President Obama's 2012 reelection effort, and was among the first high-profile Democrats to endorse him during the 2008 Democratic presidential primaries. 

This would be Kennedy's second attempt at public service, following her short-lived bid to be appointed to New York's Senate seat following Hillary Clinton's appointment as Secretary of State.
