Twitter was "bounced" from a meeting between technology company executives and Donald Trump on Wednesday because of a dispute over an emoji, Politico and Reuters reported.

The president-elect met with some of America's most powerful tech executives at Trump Tower to smooth over frictions after both sides made no secret of their disdain for each other during the election campaign.

Twitter, however, was not invited to the highly publicised summit, a move that surprised some in the industry given the president-elect's prolific use of the social media platform during his election campaign and the company's high profile in discussions over policy issues such as cyber security and the spread of violent online propaganda.
