I've seen this in a couple places. And there's video of Trump's comments.
Seems Mr. Trump proposes to lower the bar on libel laws as a way to avoid negative coverage in the future.
It's hard to tell at this point, but Trump's priority seems to target a chill the practice of First Amendment press freedom. At the same time, if libel laws are relaxed, it would likely further enrich trial lawyers, who are historically a major source for financial donations to the Democratic Party.
Before cheering looser libel laws targeting MSM, also consider they would likely be used to target bloggers or those posting on social media, the kind of folks that don't have insurance or other resources to fight a well financed libel lawsuit.
