The Wall Street Journal first reported the news.
Google said it was continuing discussions with authorities.
The federal probe of Google reportedly focuses on search bias, advertising and management of its Android operating system. The Federal Trade Commission settled an antitrust investigation of Google in 2013 with a reprimand. The WSJ says that the states, which are led by Texas Attorney General Ken Paxton and will include NY, could file their own complaints a few months later.
President Donald Trump tweeted criticism on Saturday of tech giants Facebook Inc. and Twitter Inc., as well as Google, in reposting a comment by a conservative blogger.
Shares of Alphabet (GOOGL) fell about 1.5% in after-hours trading.
The Wall Street Journal is reporting that the U.S. Department of Justice, along with a group of state attorneys general, are likely to file antitrust lawsuits against Google as soon as this summer.
Google has already been forced to turn over more than 100,000 documents to investigators as part of the ongoing probe, and civil demands have been served to a number of related third parties. "We do not anticipate that this health event will affect our ability to pursue the investigation as planned", a spokesperson for Paxton told Business Insider this week.
Paxton said in February he has not taken any possible punishment off the table, including breaking up the search and advertising giant.
The Justice Department did not immediately reply to a request for comment.
Google said in a statement that it's engaging "with the ongoing investigations led by the Department of Justice and Attorney General Paxton" and it's focused on "providing services that help consumers, support thousands of businesses, and enable increased choice and competition".
Google's violations cut to the core of the search giant's business model, which combines its acumen in Internet Search with online advertising.
State attorneys general are also investigating the company.
