A damages trial begins Monday in a case in which a judge has already ruled that Rudy Giuliani is liable for defamation.

When Rudy Giuliani steps into federal court on Monday, the only mystery will be how severely he is sanctioned for lies about the 2020 election.

U.S. District Court Judge Beryl Howell has already found him liable for defaming two Georgia election workers — Ruby Freeman and Shaye Moss — who faced threats and harassment after Giuliani and Donald Trump falsely accused them of manipulating ballots after the 2020 election. Those lies fueled conspiracy theories that have festered to this day.

Now, a jury in Washington, D.C., will be asked to determine the amount of damages Giuliani must pay for defamation, infliction of emotional distress and other punitive costs. Freeman and Moss haven’t specified a precise amount but are instead preparing to introduce expert testimony to estimate the harm they have experienced.
