Today, President Trump brought an end to the Rex Tillerson era, removing him as Secretary of State after months of disagreements over everything from Charlottesville to Russia.

Why it matters: The relationship between the President and Rex Tillerson hasn't been good for months. Tillerson has broken with Trump on several important international issues and there were even reports that he had called Trump a "f****ing moron."
