When Republicans took power in the House of Representatives, they began trying to find evidence to make the case that President Biden had profited from the business dealings of his son, Hunter Biden.

They have not found that evidence, and struggled to bring public focus to their investigation – that is, until this week, when it was given the imprimatur of impeachment.

But this impeachment case is different – both in substance and in process – than the ones that loom large over the legacies of former presidents like Richard Nixon, Bill Clinton and Donald Trump.
