How Trump could reassure America's NATO allies

We reported last week that U.S. national security officials were saying one of the most urgent issues leading into the Trump-Putin summit will be Moscow's covert intrusion into American politics.

What we're hearing: Tony Blinken, who served as deputy national security adviser and John Kerry's deputy in the Obama administration, told us that Trump "has an opportunity to reverse the narrative that he's too hard on our allies and too eager to cozy up to Putin." He would do so by demonstrating a "strong, unified alliance" with NATO members and then "go to Putin and put front and center the widespread concerns across our allies about Russian meddling in our democracies."
