A noted media association is suing President Trump, claiming he’s violating the First Amendment by using his seat to “punish and stifle” news organizations.

Free speech activist group PEN America says in its Manhattan federal lawsuit filed Tuesday that Trump is violating the Bill of Rights’ protections of freedom of speech and of the press by retaliating against reporters and media outlets that cover him unfavorably.

“President Trump has First Amendment rights and is free to criticize the press vehemently, but he is not free to use the power and authority of the United States government to punish and stifle it,” the suit says.

The court papers say that Trump targets “specific outlets whose content and viewpoints he views as hostile.”

And it charges, “His actions seek to accomplish indirectly what the President cannot do directly: impede professional and investigative journalism, and silence criticism.”

The suit says Trump has tried to punish Amazon owner Jeff Bezos, who also owns the Washington Post, “whose accurate coverage of his Administration the President finds objectionable.”

Trump wanted Bezos to know that he could “use his official powers to adversely impact Amazon’s tax status and subject it to antitrust,” and these threats “caused a pronounced dip in Amazon’s stock value in July 2018,” the suit charges.

Another example of alleged retaliation for Washington Post coverage came when Trump issued an executive order to the US Postal Service to review its financial practices and to consider raising postage rates for companies like Amazon, the suit alleges.

Trump also “threatened to use the Justice Department’s antitrust merger-review process to retaliate against CNN for its news coverage” by trying to interfere with parent company Time Warner’s merger with AT&T, the court papers say.

The suit says Trump has said he would take away “White House press credentials of reporters whose coverage displeased him and has threatened to challenge NBC’s and other television stations’ broadcast licenses in relation for coverage he disliked.”

In a tweet, Trump said, “With all the Fake News coming out of NBC and the Networks, at what point is it appropriate to challenge their License? Bad for country!” the lawsuit highlights.

Trump is himself entitled to freedom of speech, which allows him to refer to unfavorable media coverage as “fake news” and to call journalists “the enemy of the American people,” the suit says. But he takes it too far, PEN claims.

“His conduct is designed to intimidate not just the specific targets of the President’s retaliatory actions and threats of action, but all who write or speak critically about the President or his Administration, including members of plaintiff Pen,” the court papers say.

PEN America, founded in 1922, is the largest of the more than 100 centers worldwide that make up the PEN International network. The group is seeking an order declaring that Trump has violated the First Amendment and an order to stop his retaliation against the media.

The Department of Justice declined to comment.
