Final answer:
The President needs approval from the Senate to appoint government officials and make treaties with foreign countries.
Step-by-step explanation:
The President has the power to appoint government officials and make treaties with foreign countries. However, these actions by the President require approval from another branch of government. To appoint government officials, the President needs the "advice and consent" of the Senate, which means a majority vote from the Senators. Similarly, to make treaties with foreign countries, the President needs a two-thirds vote of the Senate to ratify.
