I had a discussion with my buddy Fr. Ockham, who advised me as follows:

Impeachment is the process by which a legislative body addresses legal charges against a government official.

Draw strength, we don't know everything we know that Trump won, by a lot. The Politicians know more than the public about the true status of DJ Trump, he is still the legal President, not Biden.

Why else are they going down the impeachment route ?

If DJ Trump was now a civilian, they would be unable to impeach him.
