U.S. Deputy Attorney General Jeffrey Rosen made clear Monday that the Department of Justice is continuing its serious examination of antitrust issues in the online technology industry, and that it won't hesitate to expand the review into other areas.

In remarks prepared for delivery to the American Bar Association's 2019 Antitrust Fall Forum in Washington, D.C., Rosen also said, "We do not view antitrust law as a panacea for every problem in the digital world. Indeed, we will not ignore any harms caused by online platforms that partially or completely fall outside the antitrust laws. We are keeping in mind other tools in areas such as privacy, consumer protection, and public safety as part of a broader review of online platforms."

Rosen said playing a key role in both the antitrust and the broader technology review is Ryan Shores, who joined Rosen's office last month as senior adviser for technology industries. Shores, formerly a partner with Shearman & Sterling, previously clerked for the late Chief Justice William Rehnquist.
