Maggie Haberman and Katie Rogers at NYT:
President Trump has gone overseas to embark on some of the most consequential diplomatic negotiations of his tenure, threatening an all-out trade war with allies and seizing a chance to make peace with a nuclear-armed menace.
But back home, he left behind a West Wing where burned-out aides are eyeing the exits, as the mood in the White House is one of numbness and resignation that the president is growing only more emboldened to act on instinct alone.
People who did not work with Mr. Trump before the White House see his behavior as deteriorating; people who have worked for and with him for years say he has never changed, and there are simply fewer people around giving him a level of cover.
Being either ignored or attacked by Mr. Trump can be demoralizing, and the staff churn that was constant during Mr. Trump’s first year has not slowed. Kathryn Dunn Tenpas, a senior fellow at the Brookings Institution who has studied White House turnover over the last six administrations, said that Mr. Trump’s staff turnover sat at 51 percent. By the time of the midterms, Mr. Trump — who, Ms. Tenpas said, has shown a tendency to move people into new roles rather than hire from the outside — will lead an emptier White House than his predecessors had.
