If left leaning includes NBC/COmcast you are correct. NBC sat on that Trump recording for 11 years. They chose October to put it out. Thats not reporting the news. That is trying to sway a Presidential Election.
Trump worked for NBC. Of course they have recordings. And that is the one they found most offensive. There must be thousands more.
The difference between News Reporting and Propaganda is that a real news outlet would have decided to put this out last January. A left winged propaganda machine like NBC/Comcast would wait until it could cause the most damage.
