House Democrats announced Nov. 5 that they want acting White House Chief of Staff Mick Mulvaney to testify in the impeachment inquiry on Nov. 8.
“Based on evidence gathered in the impeachment inquiry and public reporting, we believe that you possess substantial first-hand knowledge and information relevant to the House’s impeachment inquiry,” House Intelligence Committee Chairman Adam Schiff (D-Calif), House Foreign Affairs Committee Chairman Eliot Engel (D-N.Y.), and acting House Oversight Committee Chairwoman Carolyn Maloney (D-N.Y.) said in a joint letter (pdf) sent to Mulvaney.
