[EX Q]: Gov. Jerry Brown of California  echoed those comments.
"In the United States  we have a federal system  and states have real power as do cities. And when cities and states combine together  and then join with powerful corporations  that's how we get stuff done "  he  said.
 His  speech was briefly interrupted by anti-coal and anti-fracking protesters  who held up banners and shouted "We're still in! Trump's still out!"

[EX Q]: Obama said that  Russian President Vladimir Putin  can "slip back into Cold War thinking and a Cold War mentality;"  he  also criticized Russia's controversial new law banning "gay propaganda."  He  dodged a question on whether  he  would meet with  Putin  at the upcoming G20 summit.
On the NSA programs revealed by Edward Snowden  Obama insisted  "We don't have a domestic spying program" and expressed  his  desire to see Snowden face trial "with a lawyer and due process." In one offbeat moment  Leno referred to Snowden  as well as Blackwater  as "Hessians " the German mercenaries hired by the British army during the American Revolutionary War.
If    in fact  the allegations are true  then  he  didn’t do that. And that is a huge problem because a lot of what we do depends on terrorists' networks not knowing that  in fact  we may be able to access their information.
LENO: And  Putin  seems to me like one of those old-school KGB guys.
OBAMA: Well   he  headed up the KGB. (Laughter.)
LENO: Yes. Well  that’s what I mean. Yes  that’s what I mean.  He  has that mentality. I mean  look at this picture here. You two don’t look pretty — (laughter) — you look like me and the NBC executives. What is going on there? (Laughter.) That doesn’t look like a friendly picture.
OBAMA: Well  the truth is  is that when we have meetings we can have some pretty blunt exchanges and animated exchanges. But  he ’s got — that seems to be  his  preferred style during press conferences  is sitting back and not looking too excited. (Laughter.) Now  part of it is  he ’s not accustomed to having press conferences where you’ve got a bunch of reporters yelling questions at you.
OBAMA: I think  Putin  and Russia have a big stake in making sure the Olympics work  and I think they understand that for most of the countries that participate in the Olympics  we wouldn’t tolerate gays and lesbians being treated differently. They’re athletes  they’re there to compete. And if Russia wants to uphold the Olympic spirit  then every judgment should be made on the track  or in the swimming pool  or on the balance beam  and people’s sexual orientation shouldn’t have anything to do with it.
