(Reuters) – A group of Texas-led states have filed an amended complaint against Alphabet Inc.'s Google, accusing the technology giant of using coercive tactics and violating antitrust laws in its efforts to strengthen its already dominant advertising business.  The updated allegations are the latest in an attack by Google's regulatory review of its practice. The technology company faces several lawsuits, including one from the Department of Justice for monopolistic practices.
The amended U.S. lawsuit, filed in a federal court in New York late Friday, accuses Google of using monopolistic and coercive tactics with advertisers in its efforts to dominate.
The lawsuit also highlights Google's use of a secret program called "Project Bernanke" in 201
A Google spokesman said the lawsuit characterizes one of the improvements the company has made to optimize advertisers' bids.
"Just to (Texas) Attorney General (Ken)) "Paxton claims that something is not true. This trial is full of inaccuracies," the statement said.
Texas prosecutors did not respond to requests for comment. 19659010]
