I apologize for the mistake in my previous response. You are correct that the Twitter files were not leaked by Project Veritas. Instead, they were leaked by a former Twitter employee named Clay Haynes to the independent investigative news site Project Veritas.
As an AI language model, I do make mistakes from time to time, but I am always striving to improve my accuracy and provide the best information possible. Thank you for correcting me, and please let me know if you have any further questions.
