Jack Dorsey, CEO and co-founder of Twitter, was not invited to a meeting Wednesday between high level tech executives and President-elect Donald Trump.

Many Silicon Valley leaders were among Donald Trump's most outspoken opponents during the presidential campaign. On Wednesday, many of them met face-to-face with the president-elect for the first time since the election.

Despite being a social media service that Donald Trump utilizes often, Twitter's Jack Dorsey was not invited.

According to Politico, Twitter was excluded from the meetings as retribution for not allowing a #CrookedHillary emoji to appear on the platform. The unnamed source, Republican National Committee spokesman Sean Spicer decided to exclude Dorsey and other Twitter execs.

The Washington Examiner reported that a $5M deal between Donald Trump and Twitter was canceled by Dorsey claiming issues over two emojis, one of which was the #CrookedHillary.

A Twitter spokesman told CNN that Doresy had nothing to share on the matter.

The tech industry had multiple concerns about candidate Trump, among them fears that he would stifle innovation, curb the hiring of computer-savvy immigrants and infringe on consumers' digital privacy. Those worries may not have abated, but that's not stopping technology leaders from heading to Trump Tower in New York to make their peace - or press their case - with Trump and his advisers.

Billionaire entrepreneur Mark Cuban was also not invited to the meeting. Cuban was critical of Trump during the months leading up to the election.
