Whether granted by himself (self pardon) or by Pence, or any future president, are such pardons prohibited by the Constitution?
US Constitution
Article 2 Section 2.
The President ,,, shall have power to grant reprieves and pardons for offenses against the United States, except in cases of impeachment.
Article 1 Section 3
Judgment in Cases of Impeachment shall not extend further than to removal from Office, and disqualification to hold and enjoy any Office of honor, Trust or Profit under the United States: but the Party convicted shall nevertheless be liable and subject to Indictment, Trial, Judgment and Punishment, according to Law.
The constitution clearly believes those impeached should suffer the consequences of their actions through both a political and legal judgement. So does article 2 section 3 preclude the derailing of a legal judgement by precluding presidential pardons to those impeached?
For what, Herr Himmler?
You vile traitors have tried to rape him for 5 years and failed.
Bullshit. Trump has been assraped multiple times, and he keeps on coming back for more. The first one was when Congress and the Senate passed a veto-proof law saying that Trump could not lift sanctions against Russia without the Consent of both the House and Senate, keeping Trump from fulfilling his promise to Putin to life sanctions after the Inaugurations, as conveyed by Gen. Flynn to the Russian Ambassador in the telephone call that resulted in federal charges.
He got ass-raped in the 2018 elections which handed the House to the Democrats, and make no mistake, Democrats wanted Trump impeached. Trump's own actions ensured that it would happen, even as Democrats decided not to impeach for the Obstruction of Justice charges coming out of the Mueller Report.
He got ass-raped bigtime in the 2020 elections, which will see him tossed out of office, and finally, subject to criminal charges on ALL of his corrupt and illegal acts while President. No President has ever been punished for corruption and criminal behaviour while as President, but then no other President was a corrupt criminal before he was elected either.
