Uber has hired the “the first lady of privacy” to help repair the car service’s tarnished image in the wake of a spying scandal.

Harriet Pearson, a partner at law firm Hogan Lovells, will lead an “in-depth review and assessment” of Uber’s privacy program, the company said on Thursday.

Uber, run by CEO Travis Kalanick, is under fire after a New York executive allegedly tracked a BuzzFeed reporter’s Uber rides without permission.

Pearson, IBM’s former chief privacy officer, earned her nickname in legal circles. She may also recommend changes to other company policies, Uber said.

Pressure on Uber intensified after Sen. Al Franken (D-Minn.) Wednesday launched an investigation into the alleged spying. Franken wrote a letter that also dinged Uber for another scandal involving its senior vice president of business, Emil Michael, who suggested the company spend $1 million to dig up dirt on the company’s critics.

Uber “will be responding to Sen. Franken’s questions in the coming weeks,” a spokeswoman said.
