Former Secretary of State Hillary ClintonHillary Rodham ClintonTrump unloads on Clinton moments after speech Clinton paints chilling image of Trump with nuclear codes Clinton links Trump debt to student loan fight MORE on Monday called for stricter sanctions on Russia after the crash of a Malaysia Airlines flight in Eastern Ukraine last week.
"We should work to bring our European allies together with us on tougher sanctions that would make it clear to [Russian President Vladimir] Putin that there is a price to pay for this kind of behavior, and we should encourage Europeans to start immediately to make sure they are less dependent on Russian energy so they are not intimidated," Clinton said during a Facebook question and answer.
"Finally, I would like to see more support given to the Ukrainians to guard their borders and to protect themselves," she said.
The United States, Ukraine and others have said there is strong evidence to suggest that pro-Russian separatists shot down the plane. President Obama and others have criticized Russia for creating an unstable climate in Ukraine by backing the militants.
The United States last week imposed its harshest sanctions yet on Russian companies before the crash. And on Monday, Obama said costs would increase for Russia if it continues to support the separatists with training and weapons.
Last week, Clinton said there was a growing awareness the separatists were involved, and the surface-to-air weapons likely came from Russia.
Clinton participated in the question and answer Monday while on a trip to Silicon Valley, visiting with Facebook, Twitter and Google.
She remained coy about her 2016 presidential ambitions but offered a few morsels, saying, "I love New Hampshire," in response to one question about visiting the first-in-the-nation presidential primary state.
Answering "hypothetically," she said at another point her priority as president would be to "grow the economy, increase upward mobility, and decrease inequality."
She also said she would consider supporting a constitutional amendment to undo the effects of a pair of Supreme Court decision that rolled back campaign finance restrictions.
Her answer, however, was more cautious than many Senate Democrats, who have vowed to vote on such a proposal.
"I would consider supporting an amendment among these lines that would prevent the abuse of our political system by excessive amounts of money, if there is no other way to deal with the Citizen's United decision," she said.
