A video of a confrontation between California’s senior senator and some earnest earth-loving tweens is sparking internet rage.

The filmed encounter shows Sen. Dianne Feinstein, an 85-year-old Democrat, talking to a group of middle-school and high-school-age kids who had come to her San Francisco office to ask her to support the Green New Deal, a package of environmental reforms targeting climate change.

After one child said, “The government is supposed to be for the people, by the people, and all for the people,” Feinstein delivered a frank retort: “You know what’s interesting about this group? Is I’ve been doing this for 30 years. I know what I’m doing. You come in here and you say it has to be my way or the highway. I don’t respond to that.”

Later in the heated exchange, a teen girl said, “We’re the people who voted you. You’re supposed to listen to us. That’s your job.” After discovering that the girl was just 16, Feinstein responded, “Well you didn’t vote for me.”

Like so many other recent viral videos, the charged exchange quickly split Twitter TWTR, +7.09% users into warring factions. Some said Feinstein, who was first elected in 1992, should resign. Others accused her of being “rude and cocky.” Others defended Feinstein and said she was “ambushed” by children who were being used a “political props.”

Feinstein responded to the criticism with a Twitter post on Friday, saying in part, “I want the children to know they were heard loud and clear.” Feinstein added that she presented the group with a draft resolution “that provides specific responses to the climate change crisis, which I plan to introduce soon.”

The group that the young people represented, The Sunrise Movement, also defended itself in the wake of the video, explaining that the film clip hadn’t been doctored.
