President Donald Trump met with Twitter co-founder and CEO Jack Dorsey at the White House, press secretary Sarah Sanders confirmed after the meeting had ended.

Shortly after Tuesday's meeting, Trump tweeted: "Lots of subjects discussed regarding their platform, and the world of social media in general. Look forward to keeping an open dialogue!"

Following the meeting, a Twitter spokesperson told NBC News that "Jack had a constructive meeting with the President of the United States today at the president's invitation. They discussed Twitter's commitment to protecting the health of the public conversation ahead of the 2020 U.S. elections and efforts underway to respond to the opioid crisis."

Trump's positive assessment of the meeting represented a reversal from his attitude toward the company just hours before, on Tuesday morning, when he used his personal Twitter account to criticize the tech giant.

There is no evidence to support Trump's claim that Twitter is "very discriminatory," or that it is "hard for people to sign on." Trump's allegation that Twitter is "constantly taking people off list," likewise appears to be unfounded, although the site does take steps to remove automated accounts that impersonate real people, known as bots. It was also unclear precisely what Trump was referring to by, "Big complaints from many people."
