WASHINGTON (AP) — Google returned to federal court Friday to fend off the U.S. Justice Department’s attempt to topple its internet empire at the same time it’s navigating a pivotal shift to artificial intelligence that could undercut its power.

A judge queried lawyers during closing arguments on Friday about how future competition should factor into his decision, which is expected by August.

The unit of Alphabet ( NASDAQ: GOOG) ( GOOGL) company expressed disagreement with the court’s earlier finding that it held an illegal monopoly, stating in a post on X that it believes the decision was flawed and looks forward to pursuing an appeal once a final opinion is issued.
