Federal appointments, Republican denials

Republican senators are blocking most of Biden's appointments to federal judgeships in the US south.

This is partly because of a rule that the Senate won't vote on a nominee unless the senators of per home state approve of per. ISTR that the Republicans abolished that rule when the corrupter became president, so they could quickly fill the backlog of vacancies that they had created by blocking all of Obama's nominations for years.

So why is that rule operating now? Did Democrats restore it?
