“Didn’t Trump pardon Flynn?”
Flynn hasn’t been charged or convicted of anything. As far as we know he is innocent.
The whole case against him is based on anonymous sources leaking to the Washington Post that Flynn omitted some information from his security clearance forms.
Only a deranged libtard thinks Trump might get impeached by his own party over this. CNN probably knows better but they are all about ratings.
IIRC, the only thing running against Flynn was the Logan Act. Once that more or less vanished, Comey started looking at process crimes, false testimony essentially. You may be right that his “false testimony” relates to routine disclosure for security purposes, but my guess is there is no case there. Not no omissions, just any omissions can reasonably be explained.
