Interest groups often use lobbying to influence members of Congress.
Explanation:
Interests groups often employ lobbying as a tactic to influence decisions of the executive or the legislature or the judiciary to make sure that the policies being made and the laws that are being passed are in their favor either strategically or economically.
Lobbying groups like big pharmaceuticals often have great influence on how laws are made and which things are outlawed or not as many people in the government also have vested interests in these groups.
