A social media company suspended its trading of Warrior trading company on Tuesday following a complaint by the Justice Department.
Twitter had previously suspended Warrior trading in January, but it had not made a decision on whether it would continue trading after the complaint.
The Justice Department said in a news release that the suspension of Warrior’s stock was in response to the Justice Dept. request for information and for “all of the information” that it “has collected.”
Warrior was founded in 2011 and offers trading of shares in energy companies, mining companies, energy-related services, and more.
The company has more than 700 employees in North America and is headquartered in Austin, Texas.
The DOJ said in the news release the company has been a major investor in the oil and gas sector, including fracking, tar sands extraction, and shale gas development.
“The Department of Justice is concerned about the continued use of Warrior stock as an instrument to facilitate the unlawful conduct of oil and natural gas extraction companies and the violation of the federal anti-corruption law, which has become a major obstacle to effective enforcement of the law,” the news office said.
“As a result of these concerns, the Department has requested that Warrior terminate its trading activity immediately.”
The Department of the Treasury Department said it is investigating the company for allegedly violating anti-money laundering laws.
The companies stock price has fallen by more than 30 percent since January.
The Department said Warrior has not responded to requests for comment.
