Well,
DU-Moron Tommy_Carcetti had you paid attention in 8th Grade history instead of making love to your

or making lust to your GF, you - and every other DU-Member - would have read it at age 13 or 14, if not earlier.
But great! What "abuse of power" did Trump commit, based on the "overwhelming evidence" gathered by Schifftyroo. Not your or Schifftyroo's Oija-Board guess of what Trump thought or meant, but what evidence proves. Evidence ... ah, there's the rub! Because the phone call transcripts and testimony of what they
saw or were instructed
by Trump disprove what Schifftyroo claims Trump thought/meant/intended. Then there's Ukrainian officials' clear statements that contradict Schifftyroo's claims ...
... and that Biden video in which he claims he arm-twisted the Ukrainian prosecutor who was investigating Burisma. That video plus various Euro countries' actions against Burisma
prove Trump's request that Ukraine investigate Burisma and the Biden's roles - criminal or not, which investigation would prove - was in the interest of the US, not an election-year gotcha (against someone who
was and is far from certain to be the Dems' nominee).
Asserting executive privilege in response to Congressional subpoenas and waiting for the courts to decide the validity of the assertions is not an "abuse of power". Executive privilege is a counter to Congressional usurpation of powers and authority delegated by the US Constitution to the President rather than Congress. Schifftyroo decided to rush ahead with what he had, not fight Trump in court, and call the product of his kangaroo-court "investigation"
overwhelming evidence.
