Sarah Paulson has offered the first glimpse of her portrait of Linda Tripp, the woman whose recordings of conversations with President Bill Clinton’s mistress, Monica Lewinsky, almost ended his administration.

Paulson said on social media that filming has begun on the Impeachment series of episodes on American Crime Story. Paulson plays the frumpy Tripp in the episodes, which examine how Tripp, a coworker of Lewinsky’s at the Defense Department, began secretly recording their conversations.

Lewsinky is played by Booksmart‘s Beanie Feldstein. The Impeachment series will track the three perspectives of Lewinsky, Tripp, and Annaleigh Ashford’s Paula Jones, who sued Clinton for sexual harassment.
