I will never understand this constant parade of Republicans who keep saying that they have this evidence, or that evidence, that is always coming 'tomorrow' and yet never seems to pan out. Why would anyone warn the people they are about to prosecute about all the tons of evidence you hold against them? Why tell them? Why tease the public with this crap.
If you really have all the evidence to sink them, then just STFU until you are ready to move and drop the bomb then. I just don't understand this piecemeal teasing that seems to go on constantly. ("Indictments are coming soon!")
If you are ready to shoot, then shoot. If not, then keep quiet until you are ready. It's just common sense.
