More than 32 tons of marijuana were found last week in an underground tunnel along the U.S.-Mexico border. It was one of the largest pot busts in U.S. history. Host Audie Cornish talks with Derek Benner, a U.S. Immigration and Customs Enforcement special agent, about the tunnel they found and the seasonal aspects of the drug trade.

AUDIE CORNISH, HOST:

Now, to a tiny village here in the U.S. attempting to solve an environmental challenge. Nestled in the remote valley in Washington's Cascade Mountains, Holden Village is about to be flooded with hundreds of workers there to clean up the contaminated remains of an old copper mine.

Anna King, of the Northwest News Network, reports on what the cleanup will cost the town.

In Durban, South Africa, thousands of men and women poured into the streets in front of the International Conference Center, where United Nations talks about climate change are taking place. Host Audie Cornish speaks with NPR's Richard Harris, who is at the conference.

Mexican drug cartels have found a new source of labor to backpack marijuana into the United States: illegal immigrants.

Federal agents, prosecutors, defense attorneys and migrants themselves say that traffickers have begun recruiting undocumented immigrants at the border, both voluntarily and forcibly. Now, U.S. courts along the border have to decide what to do with terrified immigrants who come before them and say, "The cartel made me do it."

December marks the beginning of the end of the U.S. war in Iraq.

The withdrawal has already begun as hundreds of U.S. troops are leaving Iraq every day; military vehicles, personnel and weapons are being shipped out of the country, and by Dec. 31, all U.S. troops will be gone after a conflict that started nearly a decade ago.

NPR is taking a look back at the last eight years of the war: the turning points, the costs and expectations about what comes next.

The Beginning

In case you haven't heard yet:

Republican Herman Cain effectively ended his presidential campaign this afternoon, as the toll from allegations about sexual harassment and an affair (all of which he has denied) combined to effectively end his chances at getting the GOP nomination.

Here's how the story is playing:

-- "Campaign Over, Cain Vows To Go With 'Plan B'." (NPR.org)

Carl Jung and Sigmund Freud are known as the fathers of psychoanalysis, but they focused on different things. Freud on the sexual underpinnings of — well, almost everything — and Jung for his mystical bent and dream theories.

For years, the two were close friends and collaborators but they had a falling out that ultimately ended their relationship. And turns out, there was a woman involved. Her name was Sabina Spielren.

The stories of all three are woven together in a new film called <em>A Dangerous Method.</em>

He added 9-9-9 to the national lexicon and slipped lyrics from a Pokemon movie into his stump speeches. Now that Herman Cain has suspended his presidential campaign, we look back at just a few of its most memorable — and excruciating — moments:

1. His brain freeze on Libya. His editorial meeting with the Milwaukee Journal Sentinel on Nov. 14 made for painful YouTube watching.
