If I understand the process correctly, he will loose all his "presidential" benefits, including secret service guard. He will also stop being a threat, and Biden's administration will not have to deal with the impeachment process at the beginning, which would distract from his plans to fix the country, instead they will be able to concentrate on their agenda. That is why the impeachment process has to take place now.

Lets hope that McConnell understands they need to get rid of the buffoon, not only for the country but for the one thing they really care about, the republican party. McConnell understands very well, despite having enabled the buffoon for four years, that the buffoon has caused a lot of damage to the party, and they need to get rid of him ASAP, so my hope is that they will vote to get him out.
