Which of the following is NOT a power granted to Congress?

The statement that Congress is not granted the power to appoint judges is correct. Under the U.S. Constitution, the responsibility for appointing judges lies with the President, who nominates federal judges, including Supreme Court justices. However, these nominations must be confirmed by the Senate, which provides a system of checks and balances between the branches of government.

In contrast, the powers mentioned in the other options—regulating interstate commerce, declaring war, and levying taxes—are explicitly granted to Congress. The Commerce Clause in Article I, Section 8, permits Congress to regulate commerce among the states, enabling it to create laws that facilitate trade and economic activity. The authority to declare war is explicitly stated in Article I, Section 8, giving Congress the power to make decisions regarding military engagement. Additionally, Congress has the authority to levy taxes, also outlined in Article I, Section 8, to generate revenue for the government.

Understanding these distinctions highlights the specific powers allocated to each branch of government and emphasizes the checks and balances that are a fundamental aspect of the U.S. political system.
