Nothing.
A wackjob with a big mouth was investigated to see if he is more than just a sack of hot air. The Secret Service has kept up with potential threats on the President for years.
They do this by, among other things, keeping in touch with nut cases and trying to sort out the harmless cranks, like this gy apprently is, from the actually dangerous people.
This Michale Moore, like the pompous film maker, is apprently a little disappointed that the American people over whelomingly reject his extremist pov.
He apparently showed himself to be just another blow hard and was left alone.
His house was not broken into, he was not abused, the agents forced no entry into his house, and they left.
And now this wackjob wants to pretend like he has been abused.
lol@him.
