Using the powers of government for personal political revenge:

President Donald Trump directed the Justice Department to investigate former Homeland Security official Miles Taylor over his “anonymous” essay and book hammering Trump during his first term. Trump went so far as to accuse Taylor of committing treason, a capital offense, for writing about what he saw during Trump’s first term.

Trump also ordered the DOJ to investigate Chris Krebs, Trump’s election security director during his first term. Trump wildly suggested Krebs was part of an effort to steal the 2020 election as Krebs repeatedly said there was no evidence of fraud that he could find.
