Gary Gensler, Chair of the U.S. Securities and Exchange Commission, takes his seat before the start of the Senate Banking, Housing, and Urban Affairs Committee hearing on Oversight of the U.S. Securities and Exchange Commission on Tuesday, Sept. 14, 2021.

SEC Chair Gary Gensler is testifying in the House Appropriations Subcommittee on Financial Services and General Government at 10 a.m. ET Wednesday.

The head of the Securities and Exchange Commission is likely to face questioning by several House members who are unhappy with his aggressive regulatory agenda, which some believe is now threatening to inundate the business world with a tidal wave of new rules around climate disclosure, ESG, shortening the settlement cycle, updating electronic record keeping, cryptocurrencies and many other issues.
