"Clinton falsely stated that Tulsi—an Army National Guard officer and U.S. Congresswoman who has spent her entire adult life serving this country—is a 'Russian asset.'"
So right off the bat, Tulsi's lawsuit fails because Clinton didn't actually say the thing Tulsi is claiming is defamatory.
Notably, Tulsi's brief substitutes "Republicans" with "[they]" to falsely imply she meant the Russians.
But right out the gate this fails because Tulsi is lying about what Clinton said.
