I don't expect you to be able to acknowledge the fact that we have video of those kids literally shouting build the wall, or to acknowledge the fact that there were ~100 kids shouting all manner of things. Mostly, it's just amusing to see Trump supporters suddenly completely change their threshold of what 'truth' actually is.

Where's Donald Trump's tape of muslims cheering in the streets in New Jersey after 9/11?

Where are his tax returns he said he would release?

Why did they doctor a video about Jim Acosta?

Where's the proof of Trump's claims that Florida ballots were 'massively infected?'

Where are the 4 million illegal voters?

Where's his proof that his tiny inauguration was the largest of all time?

I've watched the videos, and I saw nothing that disproves the claims made against the children directly by Phillips. That other people extrapolated further is on them, but what he said, so far, has not been shown to be false in any way.
