Contrary to what President* Trump would hope, today's firing of FBI director James Comey will not make the Russia scandal go away. It might delay an imminent indictment, and it might cripple the FBI by replacing Comey, who seemed reasonably willing to conduct an investigation of the Trump administration, with a puppet who will probably do nothing for a while, and then silently terminate all investigations into the matter. However, the story is a lot bigger than the FBI, and much too public for it to disappear. Several investigations are being conducted by Congress, and the President has no formal power over them. Investigative journalists are not going to back away either.
Firing James Comey now, when he appeared to be getting close in his investigation on Trump and Russia, is highly suspicious. The stated reason for his termination was alleged misconduct way back in July 2016. The real reason is more likely that FBI was on to something. Firing Comey for getting too close for Trump's comfort is an obvious obstruction of justice, and it only serves to borrow some more time before the Trump presidency comes to its inevitable, premature and dishonorable end.
Trump may have dodged a bullet this time, but there is a barrage of incoming fire ahead.
