I first heard about this particular conspiracy theory a little over a year ago, from Caitlin Graf, who does publicity for The Nation. She sent over an online post that compared an old picture of me—from long before I got bifocals—with that of an alleged protester. The argument was that we might be the same person because we had similar glasses and facial features. I didn’t know if the picture of the protester was legitimate, or if I have a doppelgänger. But I certainly knew that I hadn’t been at the Capitol that day. So did Caitlin and other folks at The Nation who had helped edit and amplify the journalism that our staff produced on one of the busiest days in the magazine’s history.

I sent a DM to the person who was speculating about me and explained I wasn’t in DC on the 6th. He responded politely, saying he’d note my clarification, and I didn’t hear much more about the matter. Things would show up on Twitter now and again. But the references were rare and seemingly inconsequential. So that was that.

Until the other day, when I got a call from Rachel Weiner, an able reporter for the Post who was following Trump’s D.C. case and had found the reference to me in the paperwork filed by his lawyers. I didn’t know how it got there, but I was delighted to talk about what I was doing on January 6, 2021.

To clear up any confusion on the part of the former president or his lawyers, I was in Madison, Wis., the city where I’ve written about politics for The Nation for the past two decades. That morning, I was up early to check on the final results from the Georgia runoff elections that gave Democrats control of the US Senate. That was a big story but, as someone who had written a book on the contested election of 2000, along with dozens of articles on the Electoral College and the arcane processes by which the votes that choose the president are counted, I was also excited to settle in and watch C-SPAN’s coverage of the congressional review of the electoral votes from across the country. But first I had to take my daughter to the orthodontist on the east side of Madison. That meant I missed Trump’s rally on the Ellipse, but I wasn’t bothered by that; I hadn’t expected that it would turn into such a big deal.

By the time I got home, it was almost noon in Madison, and the count, with all its pomp and circumstance, was beginning. Like most Americans, I was initially confused when the process was interrupted and Vice President Mike Pence and members of Congress were swept out of the room. But it quickly became clear that this was not going to be a traditional review of reports from the states.

My first instinct was to start calling people in D.C. I had a long conversation with US Representative Mark Pocan (D-Wis.) who was in his office on Capitol Hill. Once we’d established that he was safe and could talk, we reviewed what had happened so far. By then, Pocan and I both knew the basics of what had happened and were already talking about potential consequences. I’ve written several books dealing with presidential accountability, including a popular history of the impeachment process, so I was interested in whether House members were talking about holding Trump to account for inciting an insurrection in the last days of his presidency. I got my answer quickly. Newly elected US Representative Mondaire Jones (D-N.Y.) called for impeachment within minutes of the disruption of the count, and not long after that US Representative Ilhan Omar (D-Minn.) signaled that she would be drawing up articles of impeachment. At about 1:30 my time, I reached out to US Representative Ro Khanna (D-Calif.), who was sheltering in the Cannon House Office Building, and it became clear to me that members of Congress were already weighing questions of whether to censure or impeach, or perhaps encourage Trump’s cabinet to invoke 25th Amendment’s provisions for removing presidents.

I pulled together the information I had gathered, started writing, and got a story filed to my then-editor, Anna Hiatt, by mid-afternoon. I also fit in an interview on Jeff Santos’s syndicated radio show and various other media conversations. And I joined fellow Nation writers and editor Don Guttenplan in filing short takes for The Nation’s live blog, which Jeet Heer had pulled together.

What I had to say that day about Donald Trump was tough, and it got tougher. In my columns, I wrote extensively about the impeachment power and other accountability tools. That probably didn’t make Trump or his most ardent backers view me in a favorable light, which some folks have assumed is why Trump loyalists turned their attention to me. I don’t know. But what I do know is that this is part of a very serious issue we face as a nation.

There’s a growing tendency, by folks on the right and the left, to assume that people they disagree with are always out to wreck their rivals. In addition to harming the basic workings of democracy—which require us to respect that Americans can hold radically different views and still have faith in the process—this theory narrows political discourse in a way that undermines the development of the broad coalitions that have always been needed to challenge political and corporate elites in general, and the intelligence community and the military-industrial complex in particular.

For decades, I’ve written about people from across the political spectrum who seek to build those coalitions, including conservative and libertarian-leaning Republicans, such as Rand Paul and Justin Amash, who have defended privacy rights and challenged the military-industrial complex. I’ll keep doing so, with the faith that people can disagree without despising or distrusting one another. I’d like to think that Donald Trump might even come to that conclusion, and if he did I’d be more than ready to write about it. Unfortunately for the former president, however, I’m not ready to be his alibi.
