Dorsey addressed the topic when several members of the US House of Representatives brought up a tweet with a picture threatening late Arizona Senator's John McCain daughter, Meghan, which took hours to be removed from the site. "We were slow to act, the tweet was up for 5 hours but it was way too long," he said. "Our current model works to remove content based on [user reports], but we don't believe we should put the burden of reporting content on the victim. We need to build algorithms that can recognize these issues before a human can."

Naturally, Dorsey said Twitter doesn't "feel great about this," and that the company can't use its scale as an excuse. Dorsey said efforts to clean up Twitter will likely lead to the removal of many accounts, highlighting that Wall Street probably won't appreciate that, but he views these as necessary steps to create the perfect "digital public square" for everyone "There's a perception we wont act because it's not an incentive," he said, "but we see increasing health as a growth factor, not short-term... long-term."

One of the most interesting parts of the hearing was when Rep. McKinley (R-WV) showed Dorsey recent tweets that were illegally selling drugs, such as cocaine. "I'd be ashamed if I were you," McKinley told Dorsey, to which he replied, "I agree with you. This is unacceptable." By the end of the hearing, as pointed out by the committee's chairman Rep. Walden (R-OR), the account responsible for those tweets had been removed.

"Your team has been at work," Walden said. "We appreciate that."
