You never know in retrospect whether you did or didn't do exactly the right thing, stay-at-home mothers, gone-away mothers, all ofus worry whether we should have done something differently than we did.

I think what Secretary Ash Carter is seeing, and I'm glad he is, is that we got to get NATO back working for the common defense. We've got to do more to support our partners in NATO, and we have to send a very clear message to Putin that this kind of belligerence, that this kind of testing of boundaries will have to be responded to. The best way to do that is to put more armor in, put more money from the Europeans in so they're actually contributing more to their own defense.

I think Americans have every reason to be worried about ISIS and the network of terrorist groups, because they have proven to be sophisticated and effective in wreaking violence and murder in many parts of the world, including in San Bernardino with their somehow connected radicalization of that couple there.

Let's prove that we're going to stand together, make the smart decisions that will get the economy going and growing for everybody, not just those at the top, that we will stand up against special privilege and special interest.

A group of national security experts, military intelligence experts, issued a very concerning statement about Senator Bernie Sanders's views on foreign policy and national security, pointing out some of the comments he has made on these issues, such as inviting Iranian troops into Syria to try to resolve the conflict there; putting them right at the doorstep of Israel.

I think it's important for people to say look, what does each party and each candidate have to offer for you. If you want a better future that is going to be reliant on making smart economic policies, compare my husband's eight years with Ronald Reagan's eight years. 23 million new jobs, more than seven million people lifted out of poverty.

Americans have always had innovators and entrepreneurs who built real companies and create real value, but we should not and we will not respect those who get rich by cheating everybody else.
