U.S. antitrust regulators investigating proposed mergers and allegedly anticompetitive actions have focused in recent years on potentially negative effects on workers and consumers. Antitrust experts say Vice President Kamala Harris is likely to continue that approach if she wins the presidential election.

Harris served as attorney general of California from 2011 to 2017, one of the states’ leading enforcers of antitrust laws. She was then elected to the U.S. Senate and served from 2017 until January 2021, when her term as vice president began.
