Spicer was thrown out there by Trumplthinskin to support Trump's shameless lie about the size of the crowd attending IN PERSON in DC. Trump was the one who put out the "million, million and a half" number. 

The issue revolves around the relative level of support the Trump enjoys versus what Obama had in 2009. It wouldn't surprise me at all if more people  watched online than 8 years ago. I did so myself - after all, you only have one chance to witness the beginning of the end of the modern world. But it is complete BS to try to say now that it was online viewers that Trump and Spicer were referring to on Saturday. 

This juvenile "mine is bigger than yours" nonsense shouldn't matter except that Trump and his henchpersons have made it into a big deal by lying and then suggesting that facts don't matter (or exist) and then attacking the media for reporting the facts. Trump has turned a silly dispute into a question of character and integrity.
