Problem: Congress has the responsibility to oversee federal agencies. One of those agencies is the U.S. Department of Justice. Let us pretend that the leadership of the Federal Department of Justice has possibly engaged in inappropriate communications with a foreign power in violation of departmental policy; they are accused of meeting with foreign ambassadors without having proper authorization. In answering the following, how Congress assesses the level of compliance?
What powers does Congress have over agencies in the executive branch? Where can one find these authorized powers?
