BERMAN: All right. There is breaking news this morning. A possible terror attack in France. A man suspected of launching a deadly attack against a gas factory in France. Happening in Grenoble. That suspect is now under arrest. Sources say the attacker set off several small explosions inside this chemical factory. Now the disturbing part is that a decapitated body was found near the factory. There was a note or some kind of symbol nearby as well. Stay with CNN. We're going to keep you updated as soon as we learn more. In the meantime, newly minted presidential candidate Donald Trump is threatening to sue the Spanish language TV network Univision for dropping coverage of the Miss USA Pageant, which Trump co-owns. Univision says it is responding to harsh words from Trump about Mexican immigrants at his campaign kickoff speech. This is some of what Trump said earlier this month.</s>DONALD TRUMP (R), PRESIDENTIAL CANDIDATE: They are bringing drugs, they are bringing crime, they are rapists and some I assume are good people. But I speak to border guards and they tell us what we're getting.</s>BERMAN: On Thursday, Trump spoke to Erin Burnett about the lawsuit and what he calls his love for the Mexican people.</s>TRUMP: They have a huge legal ability. You know, we're going to be suing them anyway because Univision has been, in my opinion, given instructions from Mexico to get me, not to stop so much with the border, but to stop talking about trade with Mexico and other countries, but to stop talking about trade with Mexico, because Mexico is ripping us off so badly. And again, I love Mexican people. Their tremendous spirit, tremendous -- I have great affection for the Mexican people.</s>BERMAN: Trump says Univision is reneging on what he called an iron- clad contract. Both co-hosts of the Spanish language Miss USA telecast have now dropped out. All right. Violence in the streets. Uber cars attacked. Celebrities held hostage. What ignited the mayhem? That's next.
