Sean Spicer called ProPublica a “left-wing blog.” ProPublica came back with the receipts.

White House spokesperson Sean Spicer tried to pick another fight with the media on Monday — and the media fought back. When Spicer called ProPublica, a nonpartisan, nonprofit investigative journalism outlet, a “left-wing blog,” the organization took the fight to Twitter.

Appropriately for a group that’s known for its document-based reporting, ProPublica showed its receipts.

Here’s how the fight started: During Monday’s press briefing, Politico’s Matthew Nussbaum asked Spicer about a ProPublica report from earlier in the day that revealed that President Donald Trump now can withdraw money from his businesses without disclosing it.

After facing much pressure to distance himself from his businesses throughout his campaign and following his election, Trump before his inauguration put his two adult sons in charge, an arrangement the president called a “blind trust” even though it was anything but. As Derek Kravitz and Al Shaw of ProPublica reported, however, the trust’s documents were amended in February to allow for Trump’s sons to withdraw funds and give them to Trump whenever they “deem appropriate.”

Spicer, in his characteristically combative tone, attacked the reporter asking the question, the article, and the news organization itself:

I think that you just went and started to say, “This change was made.” I'm not aware that there was any change. Just because a left-wing blog makes the point of something changing doesn’t mean it actually happened. I'm not aware that there was ever a change in the trust. And the idea that the president is withdrawing money at some point is exactly the purpose of what the trust — why a trust is set up regardless of an individual.

In response, ProPublica took to Twitter to deliver a 15-tweet thread defending its reporting. “So @seanspicer just called us a ‘left-wing blog.’ Since we’re actually in the biz of facts, we figured we’d respond w/ a few,” the tweets began. (Vox has partnered with ProPublica on some reporting projects but wasn’t involved in the investigation into Trump’s businesses.)

Regardless of whether Spicer is “aware” of it, the trust documents were amended to allow for the withdrawals. In its reporting and tweets, ProPublica linked to the documents themselves and to screenshots of the newly added clause.

ProPublica then explained how before it published the article, it reached out to the Trump Organization seeking comment, but “the Trump Organization did not answer detailed questions about the trust.”

ProPublica went on to demonstrate how over the years it has produced reporting critical of both Republicans and Democrats. “Our job always has been and will be holding *all* those in power accountable,” ProPublica wrote, providing links to various stories its reporters have written critical of the Obama administration.

Spicer’s denial and pushback in the briefing is just the latest example of a Trump administration official responding to a news article by trying to discredit the press, rather than defending its own actions. Trump’s war on the media — which he has repeatedly dubbed the “enemy of the people” — is strategic. As Vox’s Andrew Prokop explained, by attacking the press, Trump can attempt to shift attention away from his legislative failures and continuing scandals. The media becomes an easy target for Trump to jump on any time things seem to be going south.

With its tweetstorm, however, ProPublica was able to call out Spicer for his evasions in a highly public environment; as of Tuesday morning, the thread had amassed 20,000 retweets.

Will you support Vox’s explanatory journalism?

Most news outlets make their money through advertising or subscriptions. But when it comes to what we’re trying to do at Vox, there are a couple of big issues with relying on ads and subscriptions to keep the lights on:

First, advertising dollars go up and down with the economy. We often only know a few months out what our advertising revenue will be, which makes it hard to plan ahead.

Second, we’re not in the subscriptions business. Vox is here to help everyone understand the complex issues shaping the world — not just the people who can afford to pay for a subscription. We believe that’s an important part of building a more equal society. And we can’t do that if we have a paywall.

So even though advertising is still our biggest source of revenue, we also seek grants and reader support. (And no matter how our work is funded, we have strict guidelines on editorial independence.)

If you also believe that everyone deserves access to trusted high-quality information, will you make a gift to Vox today? Any amount helps.
