Did President Trump use his position to extort the Ukrainian President to do his wishes?
No. But if you disagree, please provide your evidence.
Even in the impeachment articles they voted on they didn't include extortion, so I'm curious what you know that the Democrats didn't. Please share.
The fact that other Presidents have done the same thing is a moot point. ....
No it's not really moot. The fact that you openly admit other presidents did this and that you never complained about it is peculiar. If you really believed it was a crime, why didn't you speak up? Why all of the sudden now?
