President Donald Trump's pick to lead the Securities and Exchange Commission said Thursday he has no specific plans to dismantle regulations implemented under the Dodd-Frank Act, but that the new administration wants to examine whether the 2010 law is stifling economic growth.

"Dodd-Frank should be looked at, in particular rules that have been in place as to whether they are achieving their objectives effectively," Wall Street lawyer Jay Clayton said during his Senate confirmation hearing. "But, I have no specific plans to" attack the legislation, he said.

Clayton, a Sullivan & Cromwell partner whose clients included Goldman Sachs Group and Bill Ackman's Pershing Square Capital Management, also told members of the Senate Banking Committee that his work for financial firms would be a strength should he win confirmation to run Wall Street's top regulator.

The finance industry expects Clayton to play a key role in Trump's stated goal of going after Dodd-Frank, particularly with congressional Republicans making little headway in pushing legislation that would scrap major elements of the law. In recent years, the SEC's agenda has been dominated with implementing rules required under Dodd-Frank.

Democrats have argued that Clayton's legal career representing big banks and hedge funds makes him a questionable choice to lead the SEC, because he might favor Wall Street's interests over those of investors. Republicans, meanwhile, have said his experience is exactly what the SEC needs to cut regulations they say discourages companies from using public markets to raise money.

Critics have sought to lump Clayton in with other Trump picks with deep ties to Goldman Sachs, including Treasury Secretary Steven Mnuchin, a former partner at the firm, and National Economic Council Director Gary Cohn, who was the bank's president before joining the administration.

If confirmed, Clayton would have to recuse himself for a year from matters involving Sullivan & Cromwell and companies he represented. He also would be barred from ever weighing in on specific business deals or investigations he worked on as a private lawyer.

Sen. Elizabeth Warren of Massachusetts, one of the finance industry's most relentless Washington critics, said Clayton's potential recusals could make the SEC weak on enforcement, if remaining commissioners are deadlocked on dozens of cases he has to stay away from.

"The chair is often the deciding vote," she said at the hearing. "Of course if the chair can't vote and the remaining SEC commissioners split along party lines, then major enforcement actions don't go forward, and the serious wrongdoing can go unpunished."

Clayton said that he wouldn't play favorites and that he's committed to going after misdeeds.

He also said he wants to make it more appealing for companies to sell shares to the public rather than relying on private investments.
