TOPSHOT - A September 6, 2018 illustration shows tweets from US President Donald Trump in response to an editorial in the New York Times, outside of the White House in Washington, DC. - A furious Donald Trump called September 5, 2018 for the unmasking of an anonymous senior official who wrote in the New York Times that top members of his administration were undermining the president to curb his "misguided impulses." Trump asked if the unsigned op-ed could be considered treasonous, assailed the newspaper for the "gutless" piece and questioned whether the senior official it was attributed to actually existed. "TREASON?" Trump posted in response to the article entitled "I Am Part of the Resistance Inside the Trump Administration," which claimed the president's own staff see him as a danger to the nation."Does the so-called 'Senior Administration Official' really exist, or is it just the Failing New York Times with another phony source?" Trump tweeted. (Photo by MANDEL NGAN / AFP)
