Congress can’t change the standard for libel established by NY Times v. US (actual malice/reckless disregard) but it can make all kinds of other laws involving disclosure, affiliation, agenda... Stuff like that.

Also, let's end reserved seating in the White House briefing room. Why should all networks reporting the same thing each get a seat?, it should be determined by random drawing, with bloggers and freelancers included.
