There was no coup. Conducting a legitimate investigation is not a coup. The fact is that every FBI agent is partisan in the sense they can support candidates for office and have opinions on them. There is no evidence that anyone's political beliefs played a role in the investigation. The IG found no evidence of politics even though his report was somewhat biased.
A 3 star general pleaded guilty to lesser charges of perjury. He could have been nailed for crimes in his lobbying activities which included lobbying for a terrorist sympathizer. If he had his way a political opponent of that terrorist sympathizer would have been killed if the US had sent him back. That 3 star general is scum. There was no spying on Trump's campaign. The only black eye is the fact that Trump and his supporters are willing to slime the FBI for political gain.
