Twitter was cut out of Wednesday’s tech summit with president-elect Donald Trump because of a failed emoji deal during the campaign, Politico reported.

The social media platform was told it was “bounced” from the meeting because it refused to allow an emoji version of the hashtag #CrookedHillary, a source close to the matter said.

The absence of Twitter is somewhat surprising, since Trump still strongly uses the platform as a main form of communication. The company is not a big fan of Trump and had said recently that the incoming president could be banned from the site if he violates their hate-speech policies.

The emoji incident was explained in a Medium post last month by the director of digital advertising and fundraising for the Trump campaign, Gary Coby.

Coby said Dorsey personally intervened to block the Trump campaign from launching an emoji showing a small bag of money being given away or stolen. The emoji, which was designed in different versions, showed a bag with little wings on each side. It was meant to serve as a replacement to the hashtag #CrookedHillary, which was Trump’s favorite insult towards his opponent Hillary Clinton.

"We told them it was BS and what they were doing with a public platform was incredibly reckless and dangerous," wrote Coby about the dealings between the Trump team and Twitter.

RNC spokesman Sean Spicer, who is also an adviser to the Trump transition, was the one who made the decision to refuse to invite Dorsey or other Twitter representatives to the summit, a source told Politico.

Back in October, Spicer told the Washington Examiner about the emoji fallout that "while Twitter claims to be a venue that promotes the free exchange of ideas, it's clear that it's leadership's left wing ideology literally trumps that."

What Happened at the Tech Summit

Although Trump has had some run-ins with Twitter, the company isn’t the only one in the tech industry that had public disagreements with the president-elect (i.e. Apple and Amazon). Many other tech giants attended the summit.

Those who attended the meeting were: Apple CEO Tim Cook, Facebook COO Sheryl Sandberg, Alphabet CEO Larry Page, Microsoft CEO Satya Nadella, IBM CEO Ginni Rometty, Intel CEO Brian Krzanich, Tesla's Elon Musk and Amazon’s Jeff Bezos.

Trump praised the tech leaders for their "incredible innovation" and promised to do "anything we can do" to help the industry, according to USA Today. Trump also told tech leaders to call him or his people directly if they need anything.

The tech giants sat down with Trump, Vice-President elect Mike Pence and Peter Thiel where they discussed jobs, immigration, free trade, cybersecurity and taxes with Trump.
