Two top aides to former Vice President Mike Pence testified last week to a federal grand jury in Washington investigating the events surrounding the Jan. 6 attack on the Capitol, the highest-ranking officials of the Trump administration so far known to have cooperated with the Justice Department’s widening inquiry into the events leading up to the assault.
The appearances before the grand jury of the men — Marc Short, who was Mr. Pence’s chief of staff, and Greg Jacob, who was his counsel — were the latest indication that the Justice Department’s criminal investigation into the events surrounding and preceding the riot is intensifying after weeks of growing questions about the urgency the department has put on examining former President Donald J. Trump’s potential criminal liability.
