I find it highly amusing that Donald Trump talks about "Make America Great Again." He doesn`t make a thing in America, except bankruptcies.

Learn from your mistakes, trying to figure out what the best way to go forward is.

People make mistakes and I'm certainly not saying Bernie Sanders did it for any kind of financial advantage. What we've got to do as Democrats - what we've got to do as Democrats is to be united to actually solve these problems. And what I believe is that I have a better track record and a better opportunity to actually get that job done.

Nine million people - nine million people lost their jobs [in 2008]. Five million people lost their homes. And $13 trillion in family wealth was wiped out.Now, we have come back from that abyss. And it has not been easy.

Every presidential candidate for decades has released his tax returns, and I've released 33 years of my tax returns. The American people deserve to know about our taxes. And so Donald Trump is standing in the way of precedent that goes back on both sides of aisle Democrats and Republicans, and he clearly has something that he doesn't want us to see.

Of course, the economy has not been working for most Americans. Yes, of course, we have special interests that are unfortunately doing too much to rig the game.

[Muammar] Gaddafi probably had more blood on his hands of Americans than anybody else.
