Because it can't be verified true or false. Honesty and integrity in journalism still lives, a few places.
Most leftist MSM takes an unverified and non-vetted story and just run with it, truth or not. As long as it has even the slightest chance at "harming" Trump.
How many times now have we seen this with "anonymous" sourced NYT stories?
And when they have to backtrack if not outright rescind the story, it gets page 22 coverage, and NO MSM coverage.
There track record is getting worse than Trumps commentary.
