I am unclear how he “recklessly” paved the way: if the Democratic candidate is under federal investigation, which might have led to serious action, wouldn’t it have been equally reckless to withhold that information?
Yes, Trump is a menace to humanity. Clinton, however, breached serious security rules and ignored US law regarding the handling of classified information. Had it been any one less powerful, they would not have been found guilty of reckless, but not prosecutable behavior. They would have gone to prison.
