The House Judiciary Committee subpoenaed former Trump campaign manager Corey Lewandowski and former White House official Rick Dearborn on Thursday to testify Sept. 17 about potential obstruction of justice by President Trump.
The big picture: The testimonies are part of the ongoing investigation by the committee — recently dubbed "formal impeachment proceedings" by House Judiciary Chairman Jerry Nadler (D-N.Y.) — into "obstruction, corruption and abuse of power by Trump and his associates." Unlike the other witnesses in the Mueller investigation who have been subpoenaed by the Judiciary committee, Lewandowski never worked in the Trump White House — a fact that Democrats hope will prevent the president from blocking his testimony.
