He alerted the secret service
I guess we know why Pence didn’t want to get in the car with anyone but his own secret service detail on January 6th now:
The day before a mob of President Donald J. Trump’s supporters stormed the Capitol on Jan. 6, 2021, Vice President Mike Pence’s chief of staff called Mr. Pence’s lead Secret Service agent to his West Wing office.
The chief of staff, Marc Short, had a message for the agent, Tim Giebels: The president was going to turn publicly against the vice president, and there could be a security risk to Mr. Pence because of it.
The stark warning — the only time Mr. Short flagged a security concern during his tenure as Mr. Pence’s top aide — was uncovered recently during research by this reporter for an upcoming book, “Confidence Man: The Making of Donald Trump and the Breaking of America,” to be published in October.
Mr. Short did not know what form such a security risk might take, according to people familiar with the events. But after days of intensifying pressure from Mr. Trump on Mr. Pence to take the extraordinary step of intervening in the certification of the Electoral College count to forestall Mr. Trump’s defeat, Mr. Short seemed to have good reason for concern. The vice president’s refusal to go along was exploding into an open and bitter breach between the two men at a time when the president was stoking the fury of his supporters who were streaming into Washington.
Mr. Short’s previously unreported warning reflected the remarkable tension in the West Wing as Mr. Trump and a band of allies, with the clock running out, searched desperately for a means of overturning the election. Mr. Trump grew agitated as his options closed, and it became clear that he was failing in his last-ditch effort to muscle his previously compliant vice president into unilaterally rejecting the voting outcomes in key states.
The warning also shows the concern at the highest levels of the government about the danger that Mr. Trump’s anticipated actions and words might lead to violence on Jan. 6.
It is unclear what, if anything, Mr. Giebels did with the message. But as Mr. Trump attacked his second in command — and democratic norms — in an effort to cling to power, it would prove prophetic.
A day after Mr. Short’s warning, more than 2,000 people — some chanting “Hang Mike Pence” — stormed the Capitol as the vice president was overseeing the certification of Joseph R. Biden Jr.’s victory. Outside, angry Trump supporters had erected a mock gallows. After Mr. Pence was hustled to safety, Mark Meadows, the White House chief of staff, is reported to have told colleagues that Mr. Trump said that perhaps Mr. Pence should have been hanged.
Mr. Short was asked about the conversation with Mr. Giebels during an interview with the House committee investigating the Capitol riot, a person familiar with his appearance said.
The fact that Pence hasn’t completely turned on Trump after all that perfectly illustrates what a cowardly, empty suit he is. They knew that Trump would unleash his rabid followers and he did. And yet Pence can barely bring himself to say anything about it. What a loser.
