yes he should have every problem with conducting an interview when it's widely known that it's been a witch hunt all along. since the day Trump won the nomination.
That 'witch hunt' has already nabbed a few witches, has even more witches in the boiling in the pot, has cornered the inner witch brood and has the Supreme Liar in Chief so fuckin fearful that the Mueller report will expose for all Americans to see, that Trump and his campaign colluded, obstructed justice and that Trump has engaged in many, many illegal activities throughout his life.
For the report to see the light of day, to which Trump and his surrogates are doing everything to prevent, means the END for this most disgraceful American to have ever lived.
