AT&T Inc. is cooperating with the U.S. Justice Department in its Google investigation, which is exploring whether the online search and advertising giant violated antitrust laws, according to a person familiar to the situation.

The discussions are part of a probe into Google’s digital advertising and search operations, and antitrust officials have been meeting with a range of parties, people with knowledge of the matter have said previously. That includes discussions with companies and organizations other than those that have voiced complaints about google in the past, such as Oracle Corp., News Corp. and Yelp Inc.
