McCabe said he was “singled out and treated this way because of the role I played, the actions I took, and the events I witnessed in the aftermath of the firing of James Comey,” he said in a statement last year.

…Comey also said that the process had been infected with “corrosive doubt” because of Trump’s attacks on McCabe in the past. Trump targeted McCabe in part because his wife had unsuccessfully run for state office in Virginia with support from Democrats.
