Twitter was awash with President Donald Trump’s lies early Saturday, thanks in part to conservative attorney George Conway.

The lawyer helped the #PresidentPinocchiosTopLies hashtag trend on the social media platform after Preet Bharara ― the former U.S. attorney for the Southern District of New York who was fired by Trump in 2017 ― asked followers to identify Trump’s “most demonstrably provable intentional lie as POTUS.”

Conway, who has become a fierce critic of the president despite his wife Kellyanne Conway’s role as White House counselor, suggested it would be “a 500-way tie.” By The Washington Post’s reckoning, Trump has so far told more than 12,000 lies since taking office in January 2017.
