The White House plans to order all federal agencies not to renew their subscriptions to the New York Times and the Washington Post, two papers that President Trump has repeatedly attacked for their critical coverage of his administration, the Wall Street Journal reports.

The big picture: The White House said on Tuesday that it would cancel its own subscriptions to the Post and the Times, after Trump complained that they were "fake" during an appearance this week on Fox News' "Hannity." White House Press Secretary Stephanie Grisham said in an email to the Journal: "Not renewing subscriptions across all federal agencies will be a significant cost saving — hundreds of thousands of taxpayer dollars will be saved."

Between the lines: Axios' Sara Fischer notes that the Post and the Times each make around $20 million annually by selling political and issue ads (mostly issue ads) that are geared toward reaching policy makers and opinion leaders at key D.C. institutions, including the White House and federal agencies. Hundreds of copies of the two newspapers are distributed to the White House and agencies.

These are expensive ads, and they’re typically the only types of ads with pricing that can’t be negotiated or bartered down.

In fact, the Times touts its reach into the White House when selling ads. It even created a separate D.C. edition of its paper printed out of Springfield, Virginia, just to make it cheaper to target federal agencies with ads that could be locally inserted.

The bottom line: This move, if the White House follows through on it, will have an advertising impact on the newspapers at a time when the issue advocacy market is really hot.
