Former Twitter CEO Dick Costolo compares meeting with Trump to waterboarding Dick Costolo has been critical of the president before.

 -- Former Twitter CEO Dick Costolo apparently isn't a fan of President Trump -- nor his meetings.

In fact, Costolo equates attending one of the president's meetings to physical torture.

In response to a tweet Friday night about an unconfirmed upcoming White House meeting with tech leaders -- similar to the one the president hosted in December -- Costolo wrote, "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."

The current CEO of San Francisco-based fitness start-up Chorus, Costolo has taken to Twitter before to express his disdain for the commander in chief.

Following James Comey's testimony Thursday before the Senate Intelligence Committee, he tweeted, "Comey testifies Trump lied on multiple occasions & the White House calls testimony a victory. Tells you all you need to know about Trump."

And in March, Costolo tweeted, "Trump is such a wimp. He cowers from any fight, points fingers in a loss but takes credit for any win. A coward, a loser, a two-bit punk."

In December, several tech industry leaders -- including Apple's Tim Cook, Facebook's Sheryl Sandberg and Tesla's Elon Musk -- met with Trump at Trump Tower in Manhattan to improve relations between the industry and the then-incoming president.
