...The Constitution provides that the President “shall have power to grant reprieves and pardons for offences against the United States, except in cases of impeachment.”
The power thus conferred is unlimited, with the exception stated.
It extends to every [federal] offence known to the law, and may be exercised at any time after its commission, either before legal proceedings are taken or during their pendency or after conviction and judgment.
This power of the President is not subject to legislative control. Congress can neither limit the effect of his pardon nor exclude from its exercise any class of offenders...
Then the political fallout will stomp the Dems for several election cycles. If Clintons even sneezes or jaywalks after the so called pardons I’d prosecute if was Trump. The Clintons will continue their criminality as it is their nature.
