Ten states have brought a lawsuit against Google, accusing the search giant of “anti-competitive conduct” in the online advertising industry including a deal to manipulate sales with rival Facebook.

Texas Attorney General Ken Paxton says Google is using its “monopolistic power” to control the pricing on online advertisements, fixing the market in its favor and eliminating its competition.

Google is calling the suit “meritless” and says the price of online advertising has fallen over the last decade.

According to records released by Paxton's office, Texas is suing along with Arkansas, Idaho, Indiana, Kentucky, Mississippi, Missouri, North Dakota, South Dakota and Utah.
