Democratic members of the Federal Deposit Insurance Corporation are pushing to review regulations around big-bank mergers, showing the Biden administration’s wider concern with such tie-ups.

Members of the FDIC met on 14 December for the first time since a partisan fight over mergers spilled into public view last week. Three Democratic members, including two appointed by President Biden, sought to launch a regulatory process related to mergers without the support of the chairman of the agency, a Trump-era holdover.
