A. Facebook says at least 150 million Americans saw social media posts covertly placed by Russia before the election; many were anti-Clinton. Twitter has acknowledged that fake accounts, known as “bots,” touting pro-Trump material have been connected to a Russian hacker group. Critics of Trump want to know whether that disinformation was coordinated with Trump’s campaign. Also, Trump has lavished praise on Putin despite the election meddling. And both Sessions and Trump’s son-in-law Jared Kushner failed repeatedly to promptly disclose meetings with Russian officials. A particular focus of suspicion is a Russian lawyer’s June 2016 meeting in Trump Tower with Donald Trump Jr., Manafort and Kushner. Emails show that the meeting was set up after Trump Jr. was offered damaging information about Hillary Clinton, but Trump Jr. originally said the purpose of the meeting was to discuss adoption policy. No dirt on Clinton was provided at the meeting, Trump Jr. says.
