The Missouri attorney general's office is investigating whether Google has run afoul of consumer protection or antitrust laws in the state. He says Google "collects substantial information" about consumers' use of services like the shopping search engine "Googe Shopping", and airline booking service "Google Flights".
Hawley noted Google has access to an estimated 70 percent of all card transactions in the United States, as well as online users' location, device information, cookie data, online queries and website history.
"This misappropriation hurts business and it threatens to drive Google's competitors out of the market, which in turn deprives consumers of innovation and valuable services", he says.
His office is investigating to determine if Google has violated the state's main consumer protection law. It's also looking into allegations that the company manipulates search results to favor its own websites over competitors', which has been the subject of recent scrutiny in Europe.
The company operates "in a highly competitive and dynamic environment", Patrick Lenihan said in an emailed statement.
This summer, the European Union fined Google a record $2.7 Billion for similar activities.
Hawley on Monday said he also agrees with sentiments from the White House, saying Moore has a right to defend himself against the claims reported by the Washington Post.
National regulators last probed Google in 2013, when the Federal Trade Commission (FTC) reached a settlement with the internet company.
