How does a Federal prosecutor prevent a witness in his case from speaking freely to anyone that witness damn well pleases?
Easy.
Mr. Judge/Congressman, “Their testimony many jeopardize my criminal investigation”.
Therefore, it would not be appropriate for them to disclose any information before my case is completed”.
MSNBC is covering the news big time but still says it can’t confirm it, similar to what FOX is saying...just going off the CNN report- source twitter reports
That might put a Congressional subpoena on hold, but it wouldn’t stop the witness from running his mouth on national television.
