Report: Caroline Kennedy in running for ambassador to Japan

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.

On Monday, White House press secretary Jay Carney refused 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 would be the latest in a long line of high-profile ambassadors to the nation. Former Senate Majority Leader Mike Mansfield (D-Mont.) and former Vice President Walter Mondale (D) have both served in the post, as did former Speaker Tom Foley (D-Wash.).

Kennedy was a major 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. 

Last year, Kennedy stumped for Obama in New Hampshire, considered a pivotal swing state at the time.

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 ClintonHillary Rodham ClintonPoll: Clinton, Trump in tight race nationally Clinton announces guests for first debate Clinton aide: We expect to see 'Kellyanne Conway creation' at debate MORE's appointment as Secretary of State. 

Kennedy openly announced her interest in the seat, held by her uncle, Sen. Robert F. Kennedy, but was heavily criticized for not having voted since 1988. 

Kennedy was also evasive about her political stances and financial dealings, drawing additional scrutiny from the press.
