Mike Pence’s ex-chief of staff testifies to grand jury investigating January 6

Appearance of Marc Short indicates justice department has penetrated inner circle of Trump White House in criminal inquiry

Former vice-president Mike Pence's chief of staff Marc Short appeared last week before a federal grand jury investigating events connected to the January 6 Capitol attack, indicating the justice department has penetrated the inner circle of the Trump White House in its criminal inquiry.

The appearance by Short - the top adviser to the former vice president who was also by Pence's side on the day of the Capitol attack - makes him the highest-ranking Trump White House official known to have testified before the grand jury in Washington.
