The statement came in response to calls for Twitter to take action against the president's account for a tweet threatening North Korea this weekend.
President Donald Trump speaks before signing a memorandum to expand access to STEM, science technology engineering and math, education, in the Oval Office of the White House, Monday, Sept. 25, 2017, in Washington.
In a series of tweets Monday, Twitter acknowledged Trump's tweet had caused an uproar, but said it was allowed to stay because of its "newsworthiness".
The dispute between the leaders of the US and North Korea has taken on a decidedly personal tone lately - as when Trump called Kim Jong Un "Rocket Man" during a speech at the United Nations on Tuesday.
North Korea's foreign minister says President Trump's tweets about the Korean nation amount to a declaration of war and that under global law, his country can legally shoot down US military planes - even if they're not in North Korea's airspace.
The White House called North Korea's war suggestion "absurd" and said the US would still try for peaceful denuclearization of the peninsula. Others point out that Trumps tweets are a direct violation of Twitter policies about making threats. 1/6 We hold all accounts to the same Rules, and consider a number of factors when assessing whether Tweets violate our Rules 2/6 Among the considerations is "newsworthiness" and whether a Tweet is of public interest 3/6 This has always been internal policy and we'll soon update our public-facing rules to reflect it.
"We need to do better on this, and will", the team added.
People wondered why Twitter did not remove the tweet that violated the company's rules. By doing so, Twitter's admitting it exercises at least some degree of editorial judgment and acts more like a media company, a label most social platforms have long tried to avoid.
Trump's account wasn't affected in July, when Twitter announced that it was taking action, including suspensions, on 10 times the number of abusive accounts than it did a year before.
Twitter has been subject to continued criticism over how it handles tweets from the president that some consider offensive.
