Bigger than that, they don't own a news station in DC, so they don't have beat reporters for the federal offices, white house, capitol hill, etc, as the other nets have. They don't have any international reporters. So it's a big undertaking. They could do what some small nets do and just re-write stories from various other news services. No actual on site reporting. Just rip & read. But a local station could do that if they wanted to.
I think when Westwood One had their news service they had an arrangement with CNN to get some audio. Their service was done pretty cheaply, and even then, they couldn't afford to do it.
