BERMAN: Breaking news. CNN just learning that the mother of the so-called affluenza teenager, Ethan Couch, Tonya Couch, is her name, she has been charged with hindering the apprehensive of a felon. She came back to the United States overnight. She arrived in Los Angeles. She's in the custody of the Los Angeles Police Department. You can see pictures of them arriving. She's held on $1 million bond. We're joined by CNN legal analyst, Paul Callan. Hindering the apprehension. It's a serious charge.</s>PAUL CALLAN, CNN LEGAL ANALYST: A very serious charge. It's a felony. There's prison time involved and it could be substantial prison time.</s>BERMAN: She's been charged in the United States. He's still in Mexico. We know from his case, he was convicted as a juvenile a few years ago in the United States. He violated probation as a juvenile. The punishment he can get here is actually pretty light. The most he can face is 120 days. She could be the one who gets punished the most for the shenanigans.</s>CALLAN: That's the irony. She comes back after having helped him flee to Mexico and she's facing the serious jail time in the case. What colossal bad judgment. Here he is, he gets a slap on the wrist for killing four human beings. He's on probation. She helps him, allegedly, to leave the country and sets off this whole inferno and he remains behind in Mexico. She must have been involved in that decision. She's the mother. She's got the money. Why did they leave him behind in Mexico to fight extradition? Very interesting case.</s>BERMAN: She'll have a hard case to prove she wasn't involved in that as well. Paul Callan, thank you for being with us. More breaking news. We're getting word an American has been charged with plotting a New Year's attack against civilians. New details just coming in on that, next.
