The Legislative Branch created a law
The Executive Branch administers/enforces the law
Therefore, the head of the Executive Branch is the one to praise or criticize if the enforcement of said law is not what the people want. A properly worded directive to the head of DHS could “fix” a good portion of the complaints articulated in the posted article.
For example, the President could direct DHS to approve any state’s request to privatize airport security as long as the federal TSA agents fail to detect mock security checks more than 10% of the time in those airports.
