As a general rule the national news is intended to persuade and is only informative if persuasion happens to require it.
This becomes extremely obvious when one compares the national news to the local news. The latter is relatively more concerned with informing than persuading. This was particularly clear during the 2020 protests where the national news was observably tasked with persuading viewers that these were legitimate (mostly) peaceful protests and not violent riots. Meanwhile, the local news where events were occurring provided the exceedingly valuable service of keeping people continually informed via airborne footage about where they might prefer to not go at the time.
