Lake Tahoe is one of the most regulated and carefully monitored bodies of water in the United States.................but even that can't save the largest alpine lake in North America from the ravages of plastic pollution.

Water samples show that, for the first time, microplastics---the kind that litter the world's oceans--are floating in Lake Tahoe.  Scientists aren't sure exactly how they got there, but it's not a positive sign for the lake's delicate ecosystem............so we will go In Depth.

California's schools used to be strict no drug zones, but that could be changing: new legislation would allow parents to administer medical marijuana to approved students ON school campuses, in a possible major change in policies..........but there are some issues........we'll talk to the bill's author.

As the Amazon burns, Brazil's president is demanding apologies for world leaders he feels slighted him.........and is rejecting international aid to help firefighting in the rain forest.  We'll go In Depth on the rush to put out the Amazon fires clashing with some bitter diplomacy.

And we continue our "Home for Recess" series, bringing you conversations with Southern California Congress members............today west side Democrat Ted Lieu joins us in studio to talk impeaching the president, finding a new way on immigration policies...........and his talent for being one of the best in Congress when it comes to trolling on Twitter.
