Rudolph W. Giuliani is Co-Conspirator 1.

Mr. Giuliani, the crime-fighter who rose from a federal prosecutor’s office to lead New York City at its moment of deepest crisis, is not named in the indictment that was filed Tuesday accusing his former client, Donald J. Trump, of plotting to overturn the 2020 election.

But Co-Conspirator 1, who Mr. Giuliani’s lawyer acknowledged appeared to be his client, figures in each of the three conspiracies it alleges took place — leaving open the possibility that Mr. Giuliani could be charged himself.
