Donald Trump has used executive privilege to block the release of the un-redacted Mueller report.
The full and un-redacted report was subpoenaed by the Democrats but The Attorney-General, Mr Barr, a Trump appointee, refused to comply with the order.
Committee chairman Jerrold Nadler of New York says the refusal to comply with the subpoena proves the President’s “blanket of defiance” to congress’ constitutional rights.
