You can think what you want! Donald Trump's calls were wiretapped and Leaked numerous times by A Holes in the White House, and State Department. So why on Earth would Trump JR call his Dad, and have a conversation that could be tapped, and Leaked to idiots like CNN.
Calling Mark Meadows is much safer. Also, he knew how to get in touch with him. You're just looking for people who think Like you. Then you'll agree.
