What does whitehurst mean when he says that by the time he speaks with candidates "they've already been extremely vetted"

The term "vetted" means "to make a careful examination," or "to investigate someone thoroughly." It is commonly used to ensure someone is trustworthy for a job. When Whitehurst says that the candidates have already been "extremely vetted," it is implied that the candidates were investigated to a great extent.

Answer/Explanation:

A. The American Medical Association is an interest group that contributes money to lobbying and congressional members. The Iron Triangle is demonstrated here, because the interest group is paying congressional members, who in turn promote their policy to the policy makers in the bureaucracy.

B. The behavior described in Part A can be affected by its interaction with Congress, since congressional committees are a crucial component to the iron triangle. Congress writes legislation and drafts policies, which interest groups may promote or deny, and thus, a good relationship with congressional members could further push the agenda of a certain interest group.

C. The interaction between Congress and the bureaucracy can be affected by linkage institutions, because linkage solutions can affect the public opinion. They can encourage public opinion to lean towards or against a policy that Congress and the bureaucracy are working to pass. Linkage institutions can contact congressmen and individuals working with the bureaucracy. In the context of this scenario, the linkage institution of the Aerican Medical Association can pay congressmen, possibly dependent on how much this interest group wants to pass this law. Therefore, this action can be affected by linkage institutions, and changes how congressmen interact with the people administering the policy in this scenario.
