Following the instruction of the Trump White House, a lawyer for Donald McGahn informed the House Judiciary Committee on Tuesday he will not comply with the panel’s subpoena for the former White House counsel’s testimony and records.

William Burck of Quinn Emanuel Urquhart & Sullivan, who represents McGahn, informed chairman Jerrold Nadler, D-New York, of the decision in a letter Tuesday. The letter came after McGahn missed a Tuesday morning deadline to respond to Nadler’s subpoena, likely escalating the clash between House Democrats and the White House as lawmakers demand records related to special counsel Robert Mueller III’s investigation.
