Trump says he sometimes regrets his tweets and retweets

• The president has more than 84 million Twitter followers.

What he's saying: "It used to be in the old days before this, you'd write a letter, and you'd say, 'This letter is really good.' You put it on your desk and then you go back tomorrow and you say, 'Oh, I'm glad I didn't send it,'" Trump said.

• "But we don't do that with Twitter, right? We put it out instantaneously, we feel great. And then you start getting phone calls, 'Did you really say this?'"
• "It's not the tweets. It's the retweets that get you in trouble. You see something that looks good, and you don't investigate it."

Flashback: Twitter in late May said that a Trump tweet in which he threatened shooting in response to civil unrest in Minneapolis violated the company's rules.

• The move exacerbated tensions between the social media giant and the president over the company's authority to label or limit his speech and, conversely, the president's authority to dictate rules to a private company.
