WASHINGTON — Top Justice Department officials met with 14 state attorneys general on Tuesday to weigh whether they have the right tools to confront privacy and competition concerns surrounding Facebook, Google and other tech companies that have amassed extraordinary amounts of data about their consumers and advertising markets.

Americans increasingly recognize that tech companies wield tremendous power and deserve greater scrutiny, the law enforcement officials said, and they discussed whether traditional approaches to antitrust issues were still suitable for modern disputes over privacy and the tech business model.

Xavier Becerra, the attorney general of California, cautioned against comparisons to landmark antitrust cases. “Most would agree, this is not Standard Oil, this is not even Microsoft,” he said. But, he added, “all of those situations inform you.”

The Justice Department called the conversation productive, though no decisions were made or announced. The meeting, largely a forum for officials to share ideas, sharply contrasted with Monday’s chaos at the Justice Department over the confusion of whether Rod J. Rosenstein, the deputy attorney general, would leave the job.
