"On Wednesday, The Washington Post reported that the special investigation into the Trump campaign and the Russian hacking of the 2016 election now also encompasses whether President Donald Trump might be guilty of obstruction of justice. That investigation, the report says, likely stems from Trump firing FBI director James Comey, who was in charge of the investigation into whether the Trump campaign colluded with Russia. Trump told NBC’s Lester Holt in a televised interview that he had the Russia investigation in mind when he decided to fire Comey."
