Andrew McCabe should absolutely sue the USA government for his pension. If that is all he files suit for then he is a humble man that wants no trouble in his life anymore.

However, I do believe Andrew McCabe and his wife and quite possibly the DNC and other Democratic donors can sue Donald Trump personally. He defamed Andrew McCabe and his wife for his own purposes. My understanding is that she was a very viable candidate for office in the USA. I do believe the defamation of Mrs. McCabe is of interest to the DNC.

This is a very dramatic example of how politics is not a part of the decisions of FBI agents. There is absolutely no doubt Andrew McCabe was acting in the best interest of the country and its citizens. His actions definitely maintained the integrity of the FBI.

There was an active investigation of Russia being conducted before Trump approached James Comey. What was he thinking? Trump asked Russia to intervene during this campaign. Trump's assertions about the leadership of the FBI are ridiculous. I don't see how a court of the USA would see it any other way. The FBI and other agencies of the USA government have purpose according to Congressional laws. It doesn't change because the political wind is different on Inauguration Day.

Donald Trump had a responsibility to put the FBI at ease with his presidency. Asking Russia to intervene with Russian hacking of an opposition candidate occurring and known is a huge red flag. Trump failed to put Jim Comey at ease with his leadership. Instead, he made it worse by firing Jim Comey by tweet and then invited Russians to the Oval Office to receive highly classified information. The FBI had every reason to be confrontational. The evidence continued to mount and Trump was not willing to legitimize the FBI concerns. Trump failed here and he failed incredibly.
