Answer:
Checks and Balances
Step-by-step explanation:
The president nominates all federal judges, who must then be approved by the Senate. The appointment of judges to lower federal courts is important because almost all federal cases end there. Through lower federal judicial appointments, a president “has the opportunity to influence the course of national affairs for a quarter of a century after he leaves office.” Once in office, federal judges can be removed only by impeachment and conviction.
