On Monday, the former Chief of Staff of the U.S. VP Mike Pence, Marc Short, confirmed that he appeared before the federal grand investigative panel probing the deadly 6th JAN Capitol attack and unsuccessful attempts to tilt the results of the Presidential election, 2020.

According to media reports, Marc Short’s cooperation with the Capitol Attack inquiry panel makes him the highest-ranking witness known to have appeared in the criminal inquiry into the deadly riot on the Capitol building in Washington. In addition, Short’s testimony indicates that prosecutors are inspecting thoroughly the ex-American President Trump’s White House as part of their inquiry, which has extended beyond the protestors and insurgents who attacked the Capitol.

Mr. Short told CNN anchor Erin Burnett that he could confirm that he did get a witness summon for the federal grand inquiry panel, and he cooperated with that. However, under the advice of counsel, he really couldn’t provide any details on his appearance.

“I candidly think if the rioters has gotten any closer, likely there would’ve been a massacre in the capitol”. It would have been the secret service opening fire on rioters. @marctshort tells me he’s appeared once before the Federal Grand Jury re: Jan 6.

Furthermore, a top staffer to the ex-Vice President Pence was caught by Reuters and ABC News cameras leaving the federal Court in D.C. on July 22 alongside his lawyer, Emmet Flood.

Mr. Short was in a conference at the White House 48 hours before the U.S. Capitol insurrection in which a law professor, John Charles Eastman, and the former American President attempted to urge the then-VP that he’d the authority to block the certification of the outcomes of the 2020 election. However, the U.S. Department of Justice didn’t provide any statement.

On Monday, the Wall Street Journal reported that Greg Jacob, a legal counsel to Mike Pence, the former VP during the Trump administration, was issued a subpoena in the investigation and appeared in front of the grand panel of investigators. As second top Pence advisor, Mr. Jacob played a critical part in countering attempts to encourage Mr. Pence not to certify the outcomes of the election and was part of the former President’s team that opposed fringe legal theories.

Moreover, earlier in 2022, the DOJ expanded its inquiry beyond the protestors and attackers who breached the United States Capitol Hill into sponsoring, planning, and organizing for the violent demonstration.

The DOJ has subpoenaed GOP operatives associated with the scheme to put forward fake electors, and the grand panel of investigators heard 6th JAN-related matters meets from Ali Alexander, an organizer of Stop the Steal, a campaign to boost the false conspiracy theory that widespread ballot fraud led to Joe Biden’s victory over Trump in the recent Presidential election, in June.

A video released on Monday by US Congresswoman Elaine Luria, who is serving Virginia’s 2nd District, displayed a copy of the address the-then President Trump delivered on the 7th of January last year with edits that Trump’s daughter and the former senior advisor recognized as coming from her father.
