LMAO. That's absurd.
If you had said: "Trump is the first president to be impeached for tweeting", I'd almost go along with that.
Is it absurd? They started their efforts before he was even sworn in. Then they thought they had him with "Russia, Russia, Russia" and the Mueller investigation. So now they're throwing up a Hail Mary play with the impeachment. It all started with the same reason - he was elected.
