The U.S. House Committee on Oversight and Reform has released two letters it sent to a former deputy White House counsel and President Donald Trump’s tax attorney requesting their appearance for a “transcribed interview.”

Committee Chairman Rep. Elijah Cummings made the request in separate letters sent Wednesday to former deputy White House counsel Stefan Passantino and Sheri Dillon, a partner at Morgan, Lewis & Bockius in Washington. Passantino has left the White House and is now a partner at Michael Best & Friedrich, and is outside counsel for the Trump Organization.
