Driving the news: The House Judiciary Committee said Monday that it was launching a bipartisan investigation into whether big tech platforms are engaged in monopolistic practices.

A person familiar with the investigation said that, in addition to public hearings, the inquiry would include requesting documents from a wide range of companies.

That could allow the committee to receive information from small competitors of the tech giants who would otherwise be wary of testifying publicly, the person said.

“Given the growing tide of concentration and consolidation across our economy, it is vital that we investigate the current state of competition in digital markets and the health of the antitrust laws,” said Rep. Jerrold Nadler (D-NY), the committee’s chairman.
