Morning Must Reads: August 13

Despite efforts by a broad swath of Republican power brokers—from conservative activists to establishment poobahs—Donald Trump isn’t going anywhere. A new CNN/ORC poll conducted after last week’s debate shows the national front-runner solidly ahead in Iowa, displacing Wisconsin Gov. Scott Walker atop the polls.

Hillary Clinton’s email troubles aren’t going away either, as federal investigators continue to probe the handling of classified information on her private server.That investigation is now extending to her top aides, who generated at least two emails that should have been marked as “top secret.” Clinton’s campaign sent an email to supporters Wednesday warning “You might hear some news over the next few days about Hillary Clinton’s emails,” seeking to mitigate the damage that the controversy is doing to her poll numbers.

Democratic candidates are struggling to respond to the concerns of the Black Lives Matter movement, as criminal justice reform takes center stage in Congress this fall. And on the cover of this week’s magazine, TIME’s Karl Vick explores what it’s like to be a cop in America one year after Ferguson.

“Rand Paul is doing so poorly in the polls he has to revert to old footage of me discussing positions I no longer hold. As a world-class businessman, who built one of the great companies with some of the most iconic real estate assets in the world, it was my obligation to my family, my company, my employees and myself to maintain a strong relationship with all politicians whether Republican or Democrat. I did that and I did that well.” — Donald Trump in a lengthy response to Sen. Rand Paul’s new ad criticizing him
