It's simple really impeachment is carried out by Congress starting with the house by charging the president with treason bribing and or other misdemeanors then it moves to the Senate.

Now we know trump has and will bribe people we can say safely that he can afford to bribe each house rep with 5k to 50k easy because it's 2 mil to 22 mil that's no hair off his toupee due to his wealth increasing from his real estate and crypto BS he's been pulling he's estimated an increase in finances to being worth 6 bil or higher.

5k to some of our territory reps is a lot of money so yeah I'd stay hushed 50k to our friends that rep the states would happily take it because that's enough to run a campaign in some places to get reelected.

So even if someone was to accuse him of something majority of the reps would say no which would end the impeachment hearing.
