Ahead of the one-year anniversary of the U.S. Capitol riot, Twitter Inc created a new team to review the social networking site for harmful content associated with the event, the company said on Tuesday.

Social media platforms including Twitter and Facebook were accused of enabling extremists to organize the siege on Jan. 6, 2021, when supporters of then-President Donald Trump stormed the Capitol to block Congress from certifying Joe Biden's presidential election victory.

Twitter said it "convened a cross-functional working group" comprised of members across its site integrity and trust and safety teams. The group's work is specific to the anniversary of the attack on the Capitol and will watch for risks such as tweets and accounts that incite violence. The company did not say how many people were on the monitoring team.
