White House Chief of Staff Reince Priebus and President Donald Trump’s chief strategist Steve Bannon confronted Anthony Scaramucci in the West Wing on Friday morning, threatening to block the financier’s appointment as Trump’s communications director. Scaramucci laughed it off, according to a person familiar with the exchange, because he knew something they didn’t: He already had the job.For Scaramucci, the appointment completed a remarkable journey that saw him rumored for one senior administration job after another only to see the offers slip away amid internal opposition from Priebus and others.Now the telegenic Scaramucci, a fast-talking fixture on the international circuit from Davos, Switzerland, to his own lavish hedge fund conference in Las Vegas, is at the center of power in the chaotic Trump White House.
