Final answer:
The Senate is responsible for confirming presidential appointments, a process that follows nomination by the President as part of the checks and balances system.
Step-by-step explanation:
The job of confirming presidential appointments, such as federal judges and Supreme Court justices, belongs to the Senate. The Constitution specifies that the President nominates judges, and these nominations must then be approved by the Senate with a simple majority vote.
This is part of the checks and balances system designed to prevent any single branch of government from becoming too powerful. The process involves the Senate Judiciary Committee, which debates and votes on the nominee before the confirmation goes to the full Senate for a vote.
