Wiretapping, wiretapping ... it is of no use. Wiretapping is mostly legal in the U.S., and if a big powerful agency does it skipping the law, why the law will be changed to render the matter mute. 

Wiretapping is of no use impeaching a president. You need to accuse him of helping a foreign enemy to hack, damage a vital American national matter. A presidential election for example. And if such a hack yielded the 'hacker' himself the great prize, well the prize will be illegal, treasonous! 

The FBI announced it has taken up this great public service task. But why now, why the offer? Simple. The Director term will end just in time for him to run for president. And a resume consisting of a line item of Trump impeachment is most welcome. Especially by the Democratic Party. They do hate the loss so very much, which of course they have to blame it on America's enemies. But America has so many enemies, which to chose? Why of course the Pentagon have chosen. They expect a big payday.
