BLACKWELL: Welcome back. We'll have more from the Republican National Convention in just a minute. But first we're following new details on the terror attack in Nice. A source close to the investigation tells CNN that the attacker recently started speaking supportively of ISIS. That's the characterization. Police also made two more arrests today in connection with Thursday's deadly attack, that's in addition to the five others already detained over the weekend. Our Will Ripley is live from Nice. So, Will, what do we know about the people in custody and what they are saying?</s>RIPLEY: So, the ex-wife who was first detained on Friday, Victor, has now been released. The four men who were detained in the overnight hours into Saturday are still in custody. We don't know if they're friends, associates, family members. And this morning Nice more arrests, two men and a woman. But again, as we've been point out, when somebody is arrested in a terror investigation in France, it essentially means they're being taken in for questioning, voluntarily or involuntarily, but it doesn't necessarily mean that charges will be filed. So, now, we have six people, five men, one woman. But whether there -- what their role if any in all of this, that's still yet to be determined by authorities, Victor.</s>BLACKWELL: All right. Will Ripley for us there in Nice with an update on those arrests -- Will, thank you so much. Back to politics. Hillary Clinton prepares for four straight days of attacks once the Republican convention kicks off tomorrow. Donald Trump already warning he plans to turn up the heat on the Democratic presumptive nominee. Cristina Alesci is following that story.</s>CRISTINA ALESCI, CNN CORRESPONDENT: Victor, that's right. Well, we're going to hear from Donald Trump, more on how Hillary is a liar, she's crooked and he's using specific examples to claim that she's just outright corrupt, next.
