WASHINGTON (AP) — A confidant of Bill Pulte, the Trump administration’s top housing regulator, provided confidential mortgage pricing data from Fannie Mae to a principal competitor, alarming senior officials of the government-backed lending giant who warned it could expose the company to claims that it was colluding with a rival to fix mortgage rates.

Emails reviewed by The Associated Press show that Fannie Mae executives were unnerved about what one called the “very problematic” disclosure of data by Lauren Smith, the company’s head of marketing, who was acting on Pulte’s behalf.

“Lauren, the information that was provided to Freddie Mac in this email is a problem,” Malloy Evans, senior vice president of Fannie Mae’s single-family mortgage division, wrote in an Oct. 11 email. “That is confidential, competitive information.”
