The Justice Department filed a historic and long-anticipated antitrust lawsuit against Google over its allegedly anti-competitive business practices, especially how it has used its search dominance in the online advertising arena to defeat its competitors, a senior DOJ official confirmed to the Washington Examiner.

The federal lawsuit, first reported on Tuesday by the Wall Street Journal, was filed in a federal court in Washington, D.C. The DOJ’s civil case against Google was signed by 11 state attorneys general from Arkansas, Florida, Georgia, Indiana, Kentucky, Louisiana, Mississippi, Missouri, Montana, South Carolina, and Texas.
