More than 300 newspapers across the country published editorials Thursday defending the freedom of the press against attacks by President Donald Trump.

The Boston Globe, which initiated the effort, said in its editorial, “This relentless assault on the free press has dangerous consequences.” Trump promptly tweeted that the Globe was in “collusion with other newspapers on free press.” He subsequently tweeted he wants “true” freedom of the press:

Last year, Trump stated: “It's frankly disgusting the press is able to write whatever they want to write. People should look into it.”

The Globe's editorial quoted Thomas Jefferson who once said, “Our liberty depends on the freedom of the press, and that cannot be limited without being lost.”
