After Flynn pardon, could Trump do the same for himself?

Analysis: renewed US speculation raises number of legal and practical questions

Donald Trump's pardon for his former national security adviser Michael Flynn has ignited speculation that he may be planning a broader swath of pardons in his last weeks in office, especially given - most controversially - his own previously expressed view that it is within his own power to pardon himself.

Trump's pardon of Flynn, who was convicted of lying to the FBI, follows his commutation of the jail sentence of his ally and self-professed political dirty trickster, Roger Stone.
