President Joe Biden on Thursday named Allison Herren Lee, a Democrat, as acting chair of the Securities and Exchange Commission.
She replaces Elad Roisman, a Republican, who was appointed acting chair by former President Donald Trump after former SEC Chairman Jay Clayton's departure in late December.
Lee will serve as acting chair until Biden's pick to head the SEC, Gary Gensler, is officially confirmed by the Senate.
"It's an honor to continue my service on the Commission in this new role," Lee said in a statement. "I have tremendous respect for my colleagues on the Commission and the exceptional staff across the agency, and look forward to working closely with them. Together we will continue the agency's work of protecting investors and ensuring market integrity."
