Obstruction of justice

The House Judiciary Committee subpoenaed former Trump administration aide Rob Porter on Monday to testify in its probe regarding possible obstruction of justice by President Trump.

Why it matters: Porter was a key witness for the obstruction portion of former special counsel Robert Mueller's investigation. He resigned from the White House last year after his 2 ex-wives came forward with abuse allegations. Porter may never have to face the committee as the White House has moved to block other former surrogates from testifying before the House Judiciary.

House Judiciary subpoenas Corey Lewandowski to testify in obstruction probe

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.
