Ivanka Trump used a personal email account to communicate with a member of President Trump’s administration, a watchdog group said Monday.

American Oversight obtained documents through the Freedom of Information Act (FOIA) that show Ivanka Trump, a senior White House adviser to her father, used a personal email account to contact Small Business Administration (SBA) Administrator Linda McMahon in February.

Ivanka Trump wrote that she wanted to “explore opportunities to collaborate” with McMahon’s department on “women’s entrepreneurship,” according to the emails released under FOIA.

“Dina [Powell, the White House deputy national security director] and I are very excited about your focus on women’s entrepreneurship and would love to assist you in any way we can,” Ivanka Trump wrote.
