A researcher at a conservative think tank has been nominated for a second time to serve on the Securities and Exchange Commission.

Hester Peirce, a senior research fellow at the Mercatus Center at George Mason University, was first nominated in October 2015, but her candidacy never came up for a vote before the full Senate.  

As a researcher at the Mercatus Center—a conservative, market-oriented think tank with ties to the billionaire Koch brothers—Peirce has been a prominent critic of the Dodd-Frank financial reform act.

As the head of the right-wing billionaire Charles Koch-funded think tank at George Mason University in suburban Washington, DC, Peirce has been one of the most prominent academic critics of the Dodd-Frank Act.

That stance has gained her the ire of Democratic Sen. Elizabeth Warren.

“It is dangerous to put anyone on the SEC adamantly opposed to financial regulatory reform,” Warren said at Peirce’s confirmation hearing.

Peirce was an attorney on Alabama Sen. Richard Shelby’s Banking Committee staff during the development of Dodd-Frank. Shelby was a member of the committee at the time and chaired it when she appeared as an SEC commissioner nominee.

For months, Peirce has been a member of the SEC’s Investor Advisory Committee, which she would likely attend as well as a commissioner to observe and comment, but without a vote.

Earlier this year, Peirce co-authored a report calling for Finra to compete with other industry self-regulatory organizations in overseeing broker-dealers. An advantage cited in taking away the monopoly would be opening broker regulation to different approaches, she argued.
