Nothing Donald Trump says to attack journalism is as dangerous as what Trump’s chairman of the Federal Communications Commission, Ajit Pai, does to attack journalism. Pai has already used his position to threaten the quality and character of the democratic discourse on the Internet—by seeking to undermine net neutrality—and now he proposes to put a corporate stranglehold on the discourse in communities across the United States.

Since 1975, the FCC has banned media cross-ownership at the local level. What this means is that—except in rare cases where waivers are issued—one company cannot own a newspaper, a television station, and radio stations in the same market. This rule was established to prevent the creation of “one newsroom” towns by media conglomerates that have for decades wanted to cut costs by buying up print- and broadcast-media outlets, combining their news operations and then dramatically reducing the number of local reporters, editors, and on-air personalities. Related rules have maintained limits on the number of radio and television stations a media company could buy up and then dumb down—by eliminating local programming and filing the airwaves with strictly formatted music and nationally syndicated (and often rigidly right-wing) talk shows

On Wednesday, Pai announced that the FCC would vote as soon as November on a proposal to eliminate the cross-ownership rules and usher in a new era of media monopoly. For the better part of two decades, efforts to gut the rules have been blocked by grassroots groups representing consumers, journalists, and democracy advocates. But Pai is moving quickly in hopes that he can avoid the sort of mass mobilization of citizens that—with an assist from the federal courts—derailed an effort by the Bush administration to overturn the cross-ownership rules.

Former FCC commissioner Michael Copps, who now advises Common Cause on media issues, calls Pai’s proposal “a virtual death sentence for local media.”

As is common with Trump appointees who advance deregulation schemes that serve the interests of monopolistic corporations, Pai is employing Orwellian doublespeak in an attempt to fool Americans into thinking he wants to open up the media landscape. “We must stop the federal government from intervening in the news business,” he told a House Commerce subcommittee oversight hearing on Wednesday.

The truth is that the assault on cross-ownership rules is the ultimate government intervention, as it will clear the way for large corporations to gobble up media outlets, consolidate newsrooms, and diminish competition. The current rules seek to encourage genuine competition and robust debate by supporting a diversity of ownership and—by extension—diverse journalism that offers differing coverage and differing perspectives on the news.

Pai’s intervention will diminish competition in communities across the country and benefit monopolistic corporations.

The move also has the potential to benefit President Trump (who has tweeted about using the FCC’s licensing process to punish media that are critical of him) and Trump allies who rage against media outlets that speak truth to their power.

As the media-reform group Free Press noted Wednesday:

Chairman Pai’s announcement follows the FCC’s moves to restore the so-called UHF discount that allows large chains to conceal the reach of their stations and to end requirements that owners of television and radio stations operate studios in or near the communities they’re supposed to serve.

Pai has close ties to the Sinclair Broadcast Group, whose proposed $3.9 billion merger with Tribune Media is now being reviewed by government agencies including the Justice Department and the FCC. Should regulators approve the deal, the resulting broadcast giant would control more than 233 local-TV stations reaching 72 percent of the country’s population, far in excess of congressional and FCC limits on national and local media ownership.

The FCC limits to Sinclair’s potential size are the same rules Chairman Pai is now seeking to undo.

Noting that “Ajit Pai’s disastrous proposal is tailor-made for Sinclair and other giant broadcast chains that push often slanted or cookie-cutter content over the public airwaves,” Free Press president Craig Aaron said:

He’s fulfilling a longstanding industry wish list and ignoring how decades of runaway media consolidation have significantly harmed local news and independent voices. The FCC has routinely failed—and been repeatedly scolded by the courts for doing so—to consider how gutting these rules will impact already abysmally low levels of broadcast ownership by women and people of color.

Aaron promised “fierce opposition at the Commission and in the courts.”

FCC Commissioner Mignon Clyburn was quick to object to Pai’s move, warning that “The already consolidated broadcast media market will become even more so, offering little to no discernible benefits to consumers.”

She’s right. But, as a Democratic appointee, she’s in the minority on the commission. That means that Pai’s initiative will be slowed only if citizens and members of Congress speak up rapidly—and loudly—in defense of the sort of media competition, open discourse, and robust debate that are essential to democracy.

“Media monopolization imperils democracy – fewer press outlets mean less of the accountability journalism that American voters depend on to cast informed ballots,” says former commissioner Copps. “Meanwhile corrupt politicians can rest easy that the depleted local press corps will be less likely to report on graft. Chairman Pai’s anti-public interest wrecking ball is poised to strike again.”
