WASHINGTON: Google’s dominance raises troubling concerns for businesses and consumers, according to a bipartisan group of attorneys general representing almost every state who launched an antitrust investigation of the search giant Monday.

Texas Attorney General Ken Paxton, a Republican, announced the probe in front of the U.S. Supreme Court building, joined by about a dozen other attorneys general. In all, 48 states are part of the investigation of the Alphabet Inc. unit, plus Puerto Rico and the District of Columbia, officials said.
