What actions can both houses of Congress undertake concerning presidential appointees?

The correct choice is rooted in the constitutional framework that governs the relationship between Congress and the Executive branch. Both houses of Congress have the authority to investigate and confirm presidential appointees, reflecting their role in providing checks and balances within the federal government.

When the president nominates individuals for certain positions, such as federal judges, cabinet members, and ambassadors, the Senate has the responsibility to conduct a confirmation process. This typically involves hearings where the nominee is questioned, after which the Senate votes to confirm or reject the appointment. The House of Representatives does not vote on these appointments but may hold investigations to gather information or express its views regarding nominations.

This process ensures that appointed officials are vetted adequately, allowing Congress to have oversight and ensure that nominees are qualified and suitable for their roles. The action of investigating can also empower members of Congress to fulfill their duty to the public by scrutinizing the president's choices closely.

The other options, such as declaring war on appointees or dismissing them directly, are either not aligned with the powers granted to Congress or do not accurately reflect the functions of Congress in relation to presidential appointees. Congress cannot overrule presidential appointments outright; instead, they can either confirm them or choose not to confirm, which effectively serves
