Hillary Clinton's book launch looks undeniably like the prelude to a presidential campaign, but despite growing buzz, Democrats are scraping together Plans B, C and D in case she doesn't run.

The former secretary of state has criss-crossed the country on a speaking tour. Political action committees have raised millions for her. And she has now written a risk-free memoir that does little to jostle the narrative that she circled the globe wielding a brand of firm but flexible U.S. power.

Hillary Clinton won't make her intentions known about a possible White House before year's end, she said in an interview broadcast Sunday.

"I will be on the way to making a decision by the end of the year," she said in a taped interview with ABC television. "Certainly not before then."

Hillary Clinton has given her most detailed account yet of the attacks in Benghazi, Libya that killed four Americans, but said she will not join the "political slugfest" over the tragedy.

In excerpts from her forthcoming memoir "Hard Choices," Clinton offered a blunt rebuttal to Republican lawmakers who have repeatedly accused her of bungling the response to the September 11, 2012 attack on the US mission and of misleading the American public.

A woman rushed past security and threw a shoe at Hillary Clinton in Las Vegas on Thursday, but it missed and the former U.S. secretary of state laughed off the incident.

The woman launched the projectile at the 66-year-old former First Lady as she was addressing a meeting of the Institute of Scrap Recycling Industries (ISRI).

Former U.S. secretary of state Hillary Clinton on Tuesday accused Russian President Vladimir Putin of attempting to "rewrite the boundaries" of post-World War II Europe.

It came as Putin signed a treaty claiming the Black Sea region of Crimea as Russian territory, as Ukraine warned the showdown had entered a "military stage" after soldiers were killed on both sides.

U.S. President Barack Obama and outgoing Secretary of State Hillary Clinton will sit down Friday for a joint television interview, U.S. broadcaster CBS announced.

The interview will be aired Sunday evening on the "60 Minutes" show, the channel said.

U.S. Secretary of State Hillary Clinton on Wednesday warned of rising militancy in the wake of the Arab Spring, in an emotional and at times heated testimony into the deadly Benghazi attack.

"Benghazi didn't happen in a vacuum," Clinton said at the start of a Senate hearing into the September 11 assault on a U.S. mission in eastern Libya.

Secretary of State Hillary Clinton will appear before U.S. lawmakers on January 22 to be quizzed about a damning inquiry into a deadly militant attack on a U.S. mission in Libya, a senator said Tuesday.

Clinton had initially been due to testify to U.S. lawmakers in late December after the scathing probe blamed "grossly inadequate" security at the diplomatic outpost in Benghazi, eastern Libya, for failing to protect staff there.

Will she, won't she, will she, won't she, will she join the dance? To borrow from "Alice's Adventures in Wonderland," that's the question on everyone's lips about Hillary Clinton and the 2016 White House race.

And just like Alice, who followed the White Rabbit down the hole into a strange and topsy-turvy universe, nothing is ever quite what it seems in Clintonland or the ever-shifting world of U.S. politics.

U.S. Secretary of State Hillary Clinton on Tuesday urged her NATO allies and Russia to press North Korea not to carry out its planned rocket launch.

"The United States is deeply concerned about North Korea's recent announcement that it plans to carry out another rocket launch," Clinton told a meeting of the NATO-Russia council.
