Q: Phoenix (CNN) When President Donald Trump's aides said he wouldn't discuss a pardon of controversial Sheriff Joe Arpaio, he did it anyway. When they warned him against lashing Arizona's Republican senators by name, he made snide allusions to them instead. And when they insisted his statements about white supremacist violence required a re-do, he declared he was right the first time. For all of Trump's bluster at Tuesday evening's campaign rally -- against the media, Democrats, and some Republicans -- a rebuke of his own staff lay just beneath the surface, the latest indication that efforts to rein him in instead cause him to act out.Trump spoke for over an hour Tuesday, hitting the media members of both partiesAides had said he would not speak about Joe Arpaio

Q: (CNN) Authorities missed an opportunity a decade ago to stop a key ISIS operative thought to be behind the Paris and Brussels attacks, a former Belgian intelligence officer says. Instead, Andre Jacob, who at the time was the head of the anti-terrorism unit for Belgian intelligence, says that Oussama Atar, believed by French authorities to be the elusive "Abu Ahmad," was incarcerated in multiple Iraqi detention centers where he became further radicalized. The Belgian-Moroccan national, now 32, would years later introduce his own family -- including his cousins, the El Bakraoui brothers who carried out the Brussels attacks -- to his extremist ideologies, according to French and Belgian authorities.Oussama Atar is wanted by authorities in connection with Paris, Brussels terror attacksAndre Jacob, a retired anti-terror expert met him in 2006; says there was an opportunity to stop Atar a decade ago
