I have a lot of experience dealing with classified material, starting when I was on the Senate Armed Services Committee going into the four years as secretary of state.

I like to remember what Michelle Obama said in her amazing speech at our Democratic National Convention: When they go low, we go high. And Barack Obama went high, despite Donald Trump's best efforts to bring him down.

It is time to pick a side.Either we stand with the gun lobby or we join the president and stand up to them.

The economy is rigged in favor of those at the top.

I'm thrilled the president [Barack Obama] has endorsed me. We started off as fierce competitors, and we've ended up as true friends and partners and worked together on so many important issues.

From the theft of confidential cables to 21st century protest movements, to development breakthroughs that have the potential to change millions of lives, we are all in uncharted territory.

I want us to do more to support people who are struggling to balance family and work. I've heard from so many of you about the difficult choices you face and the stresses that you're under. So let's have paid family leave, earned sick days. Let's be sure we have affordable child care and debt-free college.
