Remember, Trump fueled the ''Obama is NOT our legitimate President'' birther movement for years, in hindsite looking back on it, at the request of Putin more than likely 5 years ago.
ALSO remember that John Lewis has seen confidential information that we have not seen on Trump, on how Comey handled the two candidates etc also.
That being said, imo Congressman Lewis should have kept his opinion to himself, and just not have shown up if he felt that strongly about it.
Trump is the official president elect and Trump will be our LEGITIMATE president once sworn in.
Lewis should KNOW that if his opinion is correct, and Trump's team with Trump worked with/colluded with the hackers, the inside moles, the Russians in the theft and disseminating of the stolen emails through wikileaks etc....
then Trump, our legit president, will be legitimately removed from office by being impeached and we will have President Pence.
Was the whole thing unfair to Clinton, yes....but there is NOTHING Lewis can do to change that...now.
