Waiting
The source of the "pillow story" was the Owner of the ranch.
The murder theory appears to stem from the fact that John Poindexter, who owned the ranch where Scalia was staying, told a San Antonio newspaper that he and a friend of Scalia's discovered him "in bed, a pillow over his head. His bed clothes were unwrinkled."
Although a reasonable person would assume a killer wouldn't leave evidence, considering the source it can't be entirely ignored.
Trump responded. "I can't give you an answer. You know usually I like to give you answers but I literally just heard it a little while ago."
Doesn't sound like someone who bites hook line and sinker.
We'll see what happens.
