No problem for the MSM. They will "explain it" to people who don't do their own research, per the "fake but accurate" syndrome.
They will use short time reporting to avoid any debates from even RATs who may talk too much. There main line will be, as usual:
The far-right Conservatives lies and personal attacks brought this good man down, etc. Howard Dean already said on FOX "he was brought down, DC is a tough place!”
Yes, they will. And many of their viewers will suddenly see them for the liars they are. This is far worse than Dan Rather's trying to use faked docs to undermine George Bush.
In this case, Van Jones' own recorded, documented statements brought him down. You can't keep that sort of basic information hidden, even from your most ardent followers.
A lot of them will figure it out next week, or the next. When they do, they'll tune those formerly trusted voices out, and seek out better, more reliable sources of information.
