In the recent 'Funeral' episode of the show, Sue announced that she would no longer fight the glee club following the death of her sister Jean.
Instead, she claimed that she would run for the House of Representatives to fight for better healthcare and disability benefits.
Lynch told TV Guide: "I think she's somewhat softened by this blow [of losing her sister] and it might take her focus off destroying the glee club. But she won't completely change her stripes.
"She's never better than when she's fighting for a cause. So maybe it's time for a more worthy cause than just destroying a bunch of kids' dreams. She did say she's running for Congress."
Lynch also revealed that she will not take on the role of Sue when she hosts the Emmys in September.
"I don't see that happening," she said. "It feels kind of cheap to me to come out in a tracksuit for the opening number."
However, Lynch did joke about what Sue would do if she was the host, saying: "She'd insult everybody and go Kanye West, depriving everyone of their awards and giving them to herself half the time."
