"Mueller’s team has already locked in on Paul Manafort’s son-in-law, Jeffrey Yohai. And of course, Mueller is solidly focused on both Donald Trump Jr. and Jared Kushner over their meeting with Russian representatives at Trump Tower, as well as their involvement in multiple Russian-financed real estate deals. But Flynn the younger has a special reason to be worried, as Robert Mueller’s team put a new focus on social media and how it was used to spread Russian propaganda. Because no one was more engaged in spreading false narratives than Michael G. Flynn."
