Larry Klayman signed the pleading:
https://en.wikipedia.org/wiki/Larry_Klayman
He once filed a petition seeking to have Barack Obama deported. "
His litigation tactics have led to criticism and to sanctions from legal authorities[16] including a ban from appearing in two courtrooms[9] and a temporary suspension of his law license"
"Klayman has filed a number of lawsuits against political figures and governmental agencies.[9] Klayman's goal in initiating the lawsuits is often to obtain information through the discovery process, rather than to win the lawsuit.[9] Most cases brought by either Judicial Watch or Klayman himself have failed."
BTW, has any LIV player been denied the opportunity to play in a PGA event as of yet? Their LIV contracts prohibited them from playing in the Deere this week.
