Gerontocracy at the top of the U.S. Senate

Both U.S. Senate leaders are very old and cognitively not far behind the senile, demented, and corrupt 46th President.

Where is or what is actually Mitch McConnell (age 81) doing these days? Has he e.g. said anything about the Biden clan scandal lately?

We need term limits to prevent life long career politicians of which there are too many! Urgently! Maybe one of the most important reforms awaiting Western democracies!
