Sen. Elizabeth Warren’s call to break up tech companies by reversing merger and acquisition approvals could be a red flag for the industry’s in-house counsel, accounting for extra precaution in deal negotiations.

A March 8 blog post from Warren, D-Massachusetts, outlines the presidential candidate’s plan to “break up the biggest tech companies.” Warren said that, if elected, she would appoint “regulators committed to reversing illegal and anti-competitive tech mergers,” including Facebook’s acquisition of competitors WhatsApp and Instagram and Google’s acquisition of Waze.
