Can it be done? And if does President Trump have the right to select or install judges?
Of course it can be done. The congress could wipe all the courts below SCOTUS as the article said an replace the whole district system. But what it comes down to is courage. And this is the reason that the 17th amendment must be repealed and give the states legislatures back the role of appointing the Senators. Now the senators have to answer to the voters instead of the states
Congress has the authority to "Constitute Tribunals inferior to the supreme Court" (Art I, Sect 8, Para 9).
It could dissolve the 9th Circuit, and then reconstitute it as any number of new Circuits.
The President can then nominate new judges, after they've been fully vetted, to fill these open spots.
