Who’s inside Trump’s inner circle? And are his tweets losing their impact?

In his first three months, President Trump’s inner circle has faced a few shakeups. Steve Bannon and Jared Kushner remain trusted advisers, even as Bannon was removed from his seat on the National Security Council. There are rumors that White House chief of staff Reince Priebus may soon exit the administration, something the administration denies. President Trump may still be a prolific user of Twitter, but are his comments on the social media site less impactful than they once were?
