Thomas Klebanow is the paper's managing editor and is responsible for the day-to-day running of the paper portrayed by David Costibile.
Klebanow is renowned for hiring young female reporters with questionable writing skills. He worked with executive editor James Whiting at The Philadelphia Inquirer and followed him to The Baltimore Sun.
Klebanow is often left with the responsibility for cutbacks and buyouts by Whiting. He comes across as vain and lacking character strength, but he has a good sense of the bottom line and the potential of a story to draw readers. Klebanow chairs the daily budget meetings and decides how much space to allocate to each story. Klebanow is based on former Baltimore Sun managing editor Bill Marimow, whom series creator David Simon despises.
- David Costibile who plays Thomas Klebanow is known as recurring in AMC TV series Breaking Bad as Gale Boeticher.
