Hmm.
Here is an article about Popick and the USA Freedom Kids from Time Magazine last January:
Donald Trump
In April, Popick (I wonder what his nickname was in school?) spoke of how he wanted to raise money to pay the way for those celebrities that threatened to leave the country if Trump were elected:
USA Freedom Kids want to raise $1m for anti-Trump celebs | Fusion
His goal was to raise One Million Dollars. As of the date of the article, Mr. Popick reports having raised Sixty Dollars.
Does he have a basis for the lawsuit? Perhaps. But the father strikes me as a bit creepy. What would have he done with the money raised (from Go Fund Me account), if none of the celebrities he cited actually did not leave the country? Hmmmmmmmmmm? (as Rush would say).
Sounds more like he is trying to get another 15 minutes of fame.
