Impeachment was necessary

The reason to impeach a president even after he left office is that future presidents cannot commit crimes in their last year in office such as the insurrection of the 6th of January get away with it because time is short, and he can't be impeached. Also he can't run again for public office and in spite of Q Anon conspiracy theories the election was fair and honest Biden is president

             Now trump should have been impeached in his first term of office if the Democrats were not so chickenshit. He used his office to funnel money into his businesses he is guilty of tax fraud, insurance fraud and money laundering  and many other things including election fraud in 2016
