The committee issued the subpoenas to Hicks and Donaldson as part of their sweeping investigation into possible obstruction of justice, corruption and abuse of power. The subpoena to Hicks, the former White House communications director, includes a request for documents and her appearance at a public hearing next month. The subpoena for Donaldson, who was deputy White House counsel, seeks documents and her appearance at a deposition in June.

The committee asks for both to provide documents by June 4, for Hicks to appear on June 19 and Donaldson on June 24.

"As I said earlier today, the Judiciary Committee's investigation into obstruction of justice, public corruption and abuse of power by President Trump and his Administration will continue," House Judiciary Chairman Jerry Nadler said in a statement.

The committee authorized subpoenas for Hicks and Donaldson at the same time they did so for former White House counsel Don McGahn last month. McGahn defied his subpoena on Tuesday at the direction of the White House, not appearing for a scheduled hearing. Nadler has said he will move to hold McGahn in contempt of Congress because he did not appear.
