My dad is a retired detective, he said he could find the leaker in a day. I forget exactly how he said he would do it, but it was something like he would make up fake information that sounded very scandalous and just change a word or two, or a name and give people you suspect access to it, but of course each one is different so if it is released to tbe press and that info has a certain wording or name, you can trace it right back to exactly that person. I don’t know why Trump doesn’t do that, even if he has to hire a detective be should get it done and then see to it they are prosecuted to the fullest extent of the law, even charged with sedition
I read some reports a month or so ago that Trump was already doing that.
