Washington (CNN) The revolving door of the Trump White House swung again this week, with EPA Administrator Scott Pruitt resigning and former Fox News head honcho Bill Shine coming on as deputy chief of staff for communications.

Let's cover the departure first. Pruitt left after months and months of negative headlines -- primarily surrounding his apparent attempts to use his office for personal profit. According to Brookings' Kathryn Dunn Tenpas , 54% of top staffers -- including Cabinet-level officials -- have left the Trump administration to date. Among Cabinet officials, seven have now left in Trump's first 18 months in office.

And now for the arrival. Shine, after resigning last year as the co-president of Fox News following whispers that he had been involved in building the toxic culture at the network, was scooped up by Trump to serve as his de facto communications director. Shine, a close confidant of Sean Hannity, had long been expected to join the White House -- and nary an issue was raised, at least not publicly, about the circumstances surrounding Shine's departure.

Below, the week that was -- as told through 25 Trump-related headlines.
