Is apparently illegal. I never knew that. Mr Hastert is obviously being defended vigorously by the Bill Clinton defenders who seem to think lying to government official in order hide embarrassing events in ones’ past is a thing that is permitted (note, that they never seem to remember that attempting to tamper with witnesses is not that). Oh, wait. that’s not happening.
But actually, the only things Mr Hastert has been charged with so far .. are hiding money in a mattress (which is as noted illegal, … but who knew? I certainly did not) … and lying to the FBI about being blackmailed.
I do have another question about that. Look. You are being blackmailed. It is almost certain that when the authorities approach you some sensitivity is required by the authorities if they want to stop the crime of blackmail. Well. That failed utterly.
