Under the headline "Yes, All This Happened. Trump's First 2 Weeks As President" (which allows writer Jessica Taylor to throw in things other people did and associate it Trump),
She starts off noting the claims about Inauguration crowd sizes, and returns to it a few times (because Trump and his reps kept addressing it). I can believe Obama's crowd was larger. His Inauguration was especially historic, and Washington D.C. and some nearby areas have a high percentage of Democrats and government employees who directly benefit from enlarging government, as Obama promised to do, and African-Americans who felt a connection to Obama because his father was African.
It's not like Trump was promising you can keep your doctor. If he was lying, it's a rather silly lie.
The biggest news happened when Trump met that evening with both Republican and Democratic congressional leaders, reviving his unfounded claims
that there were between 3 and 5 million illegal votes cast in the 2016
election that caused him to lose the popular vote to Democrat Hillary
Clinton.
It's probably a hyperbolic statement. Trump should have left it at noting that there were probably some illegal votes cast, and, combined with the fact that if the process of electing the President was based on the popular vote he would have taken a different strategy, and he would have won a legitimate popular vote.
The fact is, California, which is where Clinton got her high numbers, 1) has millions of illegal aliens; 2) gives driver's licenses to illegal aliens; 3) has a "motor voter registration" program. Is it far fetched to think that there was significant voter fraud?
