New York State Attorney General Letitia James announced Tuesday that 47 attorneys general from states and U.S. territories plan to take part in a New York-led antitrust probe into Facebook.
The probe will zero in on whether Facebook broke any state or federal laws as a result of any anti-competitive conduct related to its dominance of social media.
"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 in a statement.
"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.
Facebook already faces a separate antitrust investigation launched by the Federal Trade Commission in July.
Facebook and its rivals, including Google, Amazon and Apple, also face a separate probe from the U.S. Department of Justice.
