WASHINGTON — President Donald Trump told Russian diplomats last week his firing of "nut job" James Comey had eased the pressure on him, even as the FBI's Trump-Russia investigation had moved into the White House, according to reports Friday that pursued the president as he began his maiden foreign trip. White House hopes that Trump could leave scandalous allegations at home were crushed in a one-two punch of revelations that landed shortly after his departure. A Washington Post report, citing anonymous sources familiar with the matter, said a senior Trump adviser is now considered a "person of interest" in the law enforcement investigation into whether Trump's campaign associates coordinated with Russia in an effort to sway the 2016 election.
