Explanation:

The constitution is above all laws in the United States, trumping city laws and state laws. Since the Federal Government is above all the local governments and it is the one with the jurisdiction over federal laws and since the constitution is the base of all law in the US and nothing can be above it, the Federal Court is the one with jurisdiction over cases about constitutional violations.
