'I know what I'm doing.': Video shows Sen. Dianne Feinstein arguing with kids on climate bill

Sen. Dianne Feinstein is under fire after video shows her arguing with children who visited her office in hopes of swaying her vote on climate change legislation.

The children were with the Sunrise Movement, a climate advocacy organization, and approached Feinstein in hopes she would support the Green New Deal, an ambitious proposal from Rep. Alexandria Ocasio-Cortez that includes an overhaul of U.S. energy that seeks to stall the effects of climate change.

"I've been doing this for 30 years. I know what I'm doing," the California Democrat told a young girl at one point while debating with the group.

The children wrote a letter to Feinstein on a poster board decorated with hard-drawn animals and flowers, asking that she support the Green New Deal.
