Bribery, extortion, perjury, obstruction of justice, and sedition are still crimes, even if committed from the White House. They have all been investigated thoroughly. He was impeached for two of the offenses already.
And? What may I ask was the outcome of those impeachments?
Also, he was impeached for obstruction of justice, but precisely
zero of the other offenses listed. And the obstruction charge was the height of inanity. In the first case, if the democrats were confident in their ability to make the case for bribery or extortion, they would have charged that. But they didn't. Instead, they made up an offense and called it "abuse of power". In the second case, they claimed "incitement", which again required considerable mental gymnastics.
And I'm sorry, but any invocation of law and order by democrats just rings hollow.
