the Office of the President of the United States gets involved, it's Political (big P). The Executive branch is all about Politics; it's politics (little p) which make POLICY. Only the most inexperienced in life would think that Presidential interventions and decisions aren't more often than not whitewashed or dressed up, couched or disguised within the context of the presented rational for a desired political result.
This is the big leagues, these activities and interferences have calculations that run far deeper than what is on the surface. Apparently you accept that the ITC Court is full of boneheads who were unable to filter through the Presidents subsequent argument in advance of reaching their own result. The traditonal court system was established as a non-political branch of Government, but the ITC is a Quazi Judicial institution that can consider political implications (ie: the "Public Interest"; and the President, by injecting his office, took it up to the highest level of Politics; through Policy.
Any and all actions and decisions that eminate from the Office of the President, or by his direct representatives, or Cabinate Secretaries, have political considerations as major (if not Central) components of their analysis.
Civics reality class is over.
