In late 2019, Fonda moved to Washington, DC, "to be closer to the epicenter of the fight for our climate," USA Today reported. To raise awareness for the climate crisis, Fonda held a series of "Fire Drill Fridays" protests that called for the end of exploring new fossil fuels.
Tomlin joined Fonda during a protest outside the US Capitol on December 27, 2019, and was arrested for civil disobedience.
A few weeks later, the duo guest-hosted an episode of "Ellen" during which they joked about Tomlin getting locked up.
"Isn't it great that we're still having firsts?" Fonda asked Tomlin.
"Well, because of you, I got arrested for the first time," Tomlin replied, later adding: "I learned a lot in the slammer."
"You were in there for two hours," Fonda, who has been arrested five times, replied.
