Do both houses of congress have to confirm the president's appointments?
According to the constitution only the senate under the checks
and balances idea
-we are studying it in US history =)
Presidential appointments of Cabinet Members, Federal Court Judges, Ambassadors, Generals and Admirals require the consent of the Senate, and presidential appointments of Vice Presidents require the consent of both Houses of Congress. The President can hire without Congressional approval assistants who do not hold positions of power, such as personal secretaries, chauffeurs and speech writers.
The US presidents have no legal control over the Conggress; however there are political and practical ways the president can exert influence over Congress. Sometimes,but certainly not always, the majority of the houses of Congress are of the same political party as the president and those members will sometimes go along with what that president wants them to do.
