Caroline Kennedy Said to Be Obama Choice for Japan Envoy
President Barack Obama plans to name Caroline Kennedy, the daughter of the late President John F. Kennedy, as the next U.S. ambassador to Japan, according to a person familiar with the matter.
While Kennedy has agreed to the posting and the president has settled on her as his choice, an announcement isn’t expected until later this month, said the person, who requested anonymity to discuss personnel matters.
Kennedy, 55, would replace Ambassador John Roos, a former technology lawyer and Obama campaign donor, as the envoy in Tokyo. In February, Bloomberg News reported Obama had signed off on Kennedy’s nomination, pending a background check.
An early backer of Obama in his 2008 run for president and a co-chairman of his 2012 campaign, Kennedy is one of several political supporters and donors being reviewed for ambassadorships to top U.S. allies. She would be the first woman to serve as American envoy to Japan.
When asked about Kennedy’s nomination yesterday, White House press secretary Jay Carney said, “I have no personnel announcements to make.”
