Short’s involvement — reported earlier by CNN, citing a source familiar with the matter — makes him the most high-profile witness known to have testified in the criminal investigation into the attack on the US Capitol. His testimony indicates that prosecutors are examining Trump’s White House as part of their investigation, which has extended beyond the rioters who breached the Capitol.
“I can confirm that I received a subpoena for the federal grand jury, and I have complied with that subpoena,” Short told CNN’s Erin Burnett on “OutFront.” “But under the advice of a lawyer, I really can’t say much more than that.”
Earlier this year, the Justice Department expanded its investigation beyond the rioters who breached the Capitol into raising funds and organizing the political rally that served as a prelude to the riot as well as efforts aimed at overturning the Electoral College vote count.
Short and his attorney, Emmet Flood, were seen Friday leaving the federal courthouse where a federal grand jury is hearing testimony related to Jan. 6 and efforts to nullify the 2020 presidential election. ABC was the first to report account of his testimony.
Short was at a meeting at the White House two days before the Capitol attack in which Trump and attorney John Eastman tried to persuade Pence that he had the power to stop certification of election results.
The Justice Department did not immediately respond to a request for comment.
The House Select Committee, which is conducting a separate and parallel investigation into Jan. 6, declined to comment. Short testified before the committee in January.
Among the lines Trump crossed out were “I call on the Department of Justice to ensure that all offenders are prosecuted to the fullest extent of the law” and “Legal consequences must be swift and firm.”
Asked by Burnett about the changes on Monday night, Short said: “Certainly there were probably people who were foolishly caught up in the events that were unfolding on the 6th. But I think it’s unfair to describe the rioters as patriots or simply to express their first amendment rights.”
