Donald Trump's frustrations boiling over after Comey dismissal

President Donald Trump has become distrustful of some of his White House staff, heavily reliant on a handful of family members and long-time aides, and furious that the White House's attempts to quell the firestorm over the FBI and congressional Russia investigations only seem to add more fuel.
Mr Trump's frustrations came to a head this week after four months in office, with the firing of FBI director James Comey, who was overseeing the probe into his campaign's possible ties to Russia's election meddling.
