President Barack Obama unveiled an aggressive new climate change strategy on Tuesday that would limit pollution from existing coal-fired power plants, and he made clear that approval of the Keystone XL pipeline depended on the project not increasing overall greenhouse gas emissions.
Obama also pledged global leadership on climate change and to redouble U.S. efforts to fight it.
Former vice president Al Gore said Obama's speech was "by far the best address on climate by any president ever."
"I thought it was a very strong speech. I think it was as far as he can go at this stage," Oscar-winning director James Cameron told CNN.
Cameron has been an outspoken environmental activist, making documentaries and even using his blockbuster movie "Avatar" to take on the issue of climate change.
"Obviously there's going to be a huge backlash from the right and from special interests. And it's going to be a battle just to accomplish what he set forth, but it's a great opening round," said Cameron.
In a 5-4 vote, Supreme Court justices limited the historic Voting Rights Act of 1965 on Tuesday, which Congress passed during the height of America's volatile civil rights movement.
"Democracy was stabbed in the heart today," said civil rights activist Rev. Jesse Jackson.
Jackson attended Martin Luther King Jr.'s historic "I Have A Dream" speech and was with him in Memphis when he was assassinated.
A lot has changed as America's struggle for equality has come a long way from where it was in the 1960s.
But Jackson said voter suppression remains a very serious problem.
"These state legislatures like Alabama, like Louisiana, they've tried to use redistricting, and they've tried to use voter suppression tactics and schemes to limit voting, and make voting more difficult," said Jackson.
Watch "The Lead" on CNN at 4 p.m. ET for our full interview with NFL player and author Chris Kluwe.
Chris Kluwe is a record-breaking NFL punter, and now the author of a new book "Beautifully Unique Sparkleponies: On Myths, Morons, Free Speech, Football, and Assorted Absurdities." The title comes an open letter Kluwe wrote in response to Maryland state delegate Emmett Burns, who criticized an NFL player for supporting same-sex marriage. After Kluwe's father protested the amount of profanity in the original letter, the NFL player posted another on his blog, swapping out the cusses for over-the-top euphemisms, like beautifully unique sparkle pony.
The book is a collection of essays, including a tongue-in-cheek piece about the day in the life of a punter, which includes having breakfast and lunch made for him, sitting through meetings, and, as he writes, "Then comes the worst part of the day: practice. I actually have to put on my cleats and go punt a football for THIRTY MINUTES."
Do NFL punters really only practice for 30 minutes a day?
"Sometimes we go 40, you know, though we got to get a massage after those days," said Kluwe, with a laugh.
In all seriousness, however, the Oakland Raiders player said punters can't punt for more than 35 minutes, "otherwise your legs are pretty much going to fall off, especially as you start getting older."
The essay, said Kluwe, is a self-deprecating look at all the hours that go into becoming a star punter.
"People don't really see that. You just kind of see the 4, or 5 plays that are on the field. But there have been thousands of hours of practice, from high school through college, all the way still into the pros," said Kluwe.
"At this point, it's mainly more keeping fundamentals and technique," said Kluwe.
