A cross section of attorneys general from around the country are joining an anti-trust investigation of Facebook led by Attorney General Letitia James, her office on Tuesday announced.

The probe, which is reviewing Facebook’s influence in online advertising, publishing and data risk, is backed by 47 state attorneys general, including James’s office.

The investigation includes a leadership team of AGs from Colorado, Florida, Iowa, Nebraska, North Carolina, Ohio, Tennessee, and the District of Columbia.

“After continued bipartisan conversations with attorneys general from around the country, today I am announcing that we have vastly expanded the list of states, districts, and territories investigating Facebook for potential antitrust violations,” James said.

“Our investigation now has the support of 47 attorneys general from around the nation, who are all concerned that Facebook may have put consumer data at risk, reduced the quality of consumers’ choices, and increased the price of advertising. As we continue our investigation, we will use every investigative tool at our disposal to determine whether Facebook’s actions stifled competition and put users at risk.”

The investigation comes at an increasingly perilous time for Facebook, which has been viewed skeptically by lawmakers in both parties for its role in political advertising and persuasion, as well as concerns from conservatives the company has purposefully downplayed right-leaning voices.

Facebook announced on Monday it removed content believed to be generated by Russians targeting the campaign of Democratic presidential candidate Joe Biden.
