The U.S. antitrust case against Google (GOOG, GOOGL) is set to expand as about a dozen states are expected to join in the litigation, Bloomberg reports.
The states, mostly led by Republicans, have been conducting a parallel investigation of Google’s online ads, paced by Texas Attorney General Ken Paxton.
How many state sign on to the federal case may be dependent on seeing the full complaint from the Justice Dept., according to the report.
Different states have focused on other parts of Google’s business, and Democratic-led states have generally sought more time to broaden the probe.
A bipartisan group of AGs is investigating conduct tied to the Android mobile operating system, though other states oppose including Android in a complaint since it would make it too broad.
Google shares wrapped after-hours trading down 0.4%.
Previous reporting had U.S. Attorney General William Barr pressing to file its case against Google quickly, over objections of career department lawyers seeking more time to build the case.
