During the second quarter of Sunday’s Redskins-Bears game, the Redskins sent an innocuous tweet from their official Twitter account (@Redskins) about a touchback on a Bears punt.

My colleague Dan Steinberg, who misses nothing on Twitter, noticed that the exact same tweet was sent — then deleted — from the purportedly third-party @redskinsfacts Twitter account at the same time. He tweeted screengrabs of the apparent goof.

As a refresher, RedskinsFacts.com launched in July 2014 as part of a campaign to defend the controversial team name from criticism. The @redskinsfacts Twitter bio describes the site as “a growing online community of passionate Washington Redskins fans and others who support the team’s use of its name and logo,” and the Redskins admitted shortly after the launch that the team had hired the communications firm Burson-Marsteller to run the campaign.

It doesn’t take a genius to deduce that Sunday’s identical tweets were likely sent by the same person, indicating that at least one member of the social team that runs the @Redskins account has access to the @redskinsfacts account. This led some sites, including SB Nation, Deadspin, Sports Illustrated and Forbes, to suggest that the Redskins’ cover had been blown, and that the team was secretly running a Twitter account supposedly managed by fans.

On Monday, the Redskins — who, again, have said they hired a PR firm to run the “Redskins Facts” campaign — attempted to explain the mistake.

“Yesterday our social media team accidentally posted a Redskins-authored tweet to the third-party Redskins Facts account, which is an account founded by alumni players and supporters and managed by a D.C. public relations firm,” a Redskins spokesman said in a statement. “It was a simple login error that was quickly corrected after the mistake was realized. The Washington Redskins have never posted content to any of the Redskins Facts digital assets, which include a Facebook page, Twitter account, and website. Official Redskins authored content can be found at @Redskins on Twitter.”

Tweeting to multiple accounts is an easy mistake for a social media manager with access to multiple accounts to make. During baseball season, the pro-Orioles hashtag #IBackTheBirds occasionally appeared in tweets originating from the @masnNationals feed, only to be deleted when the mistake was noticed. It might behoove the Burson-Marsteller social media team that runs the @redskinsfacts account to change its login information to avoid any future embarrassment.
