Could a couple of emojis be the reason Twitter CEO Jack Dorsey was missing from Wednesday's tech summit at Trump Tower?

It turns out it all may have stemmed from a disagreement over a custom #CrookedHillary emoji, according to a Politico report.

Twitter declined NBC News' request for comment over whether Emojigate was the reason for the snub. However, there's a documented history of the campaign's beef with Dorsey.

Gary Coby, Trump's director of digital advertising, wrote in a Medium post after the election about a $5 million advertising deal the campaign had with Twitter.

"Twitter — or well, Dorsey — restricted us on the most unique part of our deal, the custom hashtag emojis, of which we had two," Coby wrote.

A hand with moneybag emoji, which would have been added to the #CrookedHillary hashtag, was not approved, according to Coby, because Twitter didn't want to falsely accuse Clinton of committing a crime.

"We have had specific discussions with several political organizations, including the Trump campaign, regarding branded emojis as part of broad advertising campaigns on Twitter. We believe that political advertising merits a level of disclosure and transparency that branded political emojis do not meet, and we ultimately decided not to permit this particular format for any political advertising," a Twitter representative told The Washington Examiner in October.

While no one is publicly saying this is why Dorsey was snubbed, Coby resurfaced his article today — around the same time as the tech leaders left Trump Tower. And for a little extra flourish, he added an emoji.
