Margulies plays the wife of a cheating politician. The timely series, which begins with a husband's confession that he has cheated on his wife with prostitutes, gives a look into what could happen behind the scenes, Margulies said.
She said she found the character, who is hurt and heartbroken after learning her husband has cheated, challenging.
"We're so quick to judge anyone in that kind of a situation," she said. "I know I did when I watched them on the podium. I'd say, 'Leave.' But until you're there, you don't know."
