Obama's top foreign policy adviser Samantha Power has resigned from the Obama campaign, after a Scottish newspaper reported she called Hillary Clinton a "monster." Power, who was unpaid, initiated the move, according to the Obama campaign.
"With deep regret, I am resigning from my role as an advisor the Obama campaign effective today," Power said in a statement released by the campaign. "Last Monday, I made inexcusable remarks that are at marked variance from my oft-stated admiration for Senator Clinton and from the spirit, tenor, and purpose of the Obama campaign. And I extend my deepest apologies to Senator Clinton, Senator Obama, and the remarkable team I have worked with over these long 14 months."
Clinton campaign backers had earlier this morning called for Power, the Pulitzer-prize winning author, Harvard professor, to step down for her comments.
Obama campaign aides had little to say.
"Its very clear where she stood on this issue," spokeswoman Jen Psaki said. "And we made clear through her statement about it."
"She notified the campaign sometime this morning," Psaki added.
When asked for more details, Psaki added, "We are not going to get into the internal dynamics of the campaign."
Communications Director Robert Gibbs stressed Power was an unpaid advisor and not part of the campaign staff.
