Do federal judges answer to Congress?
NO.
It is federal judges who act as though they are kings and queens.
Actually, the courts are accountable to congress. Congress can impeach, convict and remove judges. The only court that is mandated by the constitution is the Supreme Court and it cannot be dissolved. However, congress created and can dissolve any lower federal court. If this country should ever again be blessed by almighty God and every election an honest one, I think we could easily see a Senate of at least 67 patriots and a house of at least 51% patriots, in which case the court system could be completely reformed, and all of these corrupt, partisan and STUPID judges removed from the bench.
