Step-by-step explanation:
An important function of interest groups in the policymaking process for members of Congress is that they provide expertise and knowledge of specific issues.
Interest groups are organizations that represent a particular interest or group of interests and seek to influence government policies and decisions. They are often composed of individuals with expertise and knowledge in specific areas, such as healthcare, education, the environment, or civil rights.
When interest groups provide information and expertise to members of Congress, they can help to shape policy decisions and contribute to the development of effective policies. Interest groups may also provide members of Congress with research, data, and analysis on specific issues, which can be used to inform policy decisions and legislative proposals.
While interest groups may endorse candidates and seek to influence party platforms, their primary role in the policymaking process is to provide knowledge and expertise to lawmakers and to advocate for policies that align with their interests.
