The former CEO of Twitter isn't a fan of President Donald Trump.

Dick Costolo, 53, tweeted on Friday that anyone wishing to know what it's like to meet the 45th president should 'drink a bottle of gin and waterboard yourself.'

Costolo was commenting on a report in BuzzFeed News which claimed that Trump was planning to host a White House meeting of tech executives and venture capitalists.

Alphabet Inc. Executive Chairman Eric Schmidt, Amazon CEO Jeff Bezos, Apple CEO Tim Cook, Oracle CEO Safra Catz, and IBM CEO Ginni Rommetty are among the big names expected to attend a June 19 summit at the White House, according to Bloomberg.

The executives will attend a meeting held under the auspices of the administration's new efforts to introduce innovation so as to streamline federal government services.

The effort is being led by Trump's son-in-law and senior adviser, Jared Kushner.

On June 22, another tech-themed event is scheduled to take place at the White House.

The Office of Science and Technology Policy is organizing a gathering that will address emerging technological trends including Internet of Things and commercial drones.

When someone on Costolo's Twitter feed posted the BuzzFeed article about the summit along with a photo of Trump sitting alongside tech billionaire Peter Thiel, Costolo replied: 'If you don't get invited to this meeting and want to know what it was like, just drink a bottle of gin and then waterboard yourself.'

This isn't the first time Costolo has used his Twitter account to criticize the president. In March, Costolo tweeted that Trump was a 'wimp' who 'cowers from any fight, points fingers in a loss but takes credit for any win'

This isn't the first time Costolo has used his Twitter account to criticize the president.

In March, Costolo tweeted that Trump was a 'wimp' who 'cowers from any fight, points fingers in a loss but takes credit for any win.'

'A coward, a loser, a two-bit punk,' Costolo tweeted about Trump.

Costolo was responding to a Trump tweet plugging a Fox News show hosted by Judge Jeanine Pirro.

During that particular episode which Trump promoted, Pirro called on House Speaker Paul Ryan to resign after House Republicans failed to agree on a repeal-and-replace measure that would undo Obamacare.

Costolo was CEO of Twitter from 2010 to 2015.

He is currently chief executive of Chorus, a group fitness startup that was launched this past December.

In early 2016, Costolo founded the company with $8million of his own money, according to Business Insider.

Trump, meanwhile, has perhaps the most famous and consequential Twitter account in history.

The president has credited Twitter as well as Facebook for enabling him to mount a successful campaign for the White House, according to The Verge.
