White House aides were told that all materials prepared for the president must go first to Mr. Porter for vetting and clearance. Then Mr. Kelly must sign off on them before they go to Mr. Trump’s desk. That includes news articles, according to West Wing officials who described the memos’ content — of particular importance, given the propensity for some of Mr. Trump’s staff to slip him news accounts from dubious sources that shape his thinking or prompt him to cite unreliable or inaccurate information...Mr. Priebus had tried [and failed] to take firmer control of that process after Mr. Trump’s first week in office, when Stephen K. Bannon, the recently departed chief strategist, and Stephen Miller, the president’s senior policy adviser, pushed across the president’s desk two orders redesigning the National Security Council, and putting in place the first, court-contested travel ban on seven predominantly Muslim countries.
