House Republicans are set to hold their first hearing on Thursday for an impeachment inquiry into President Biden.

It's an impeachment case that is different — both in substance and in process — from the ones that loom large over the legacies of former presidents like Richard Nixon, Bill Clinton and Donald Trump.

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

They have not found that evidence. But the imprimatur of impeachment has increased public focus on their investigation.
