Kamala Harris joins CNN climate change town hall after criticism from activists

What they're saying: "We were happy to change our schedule to accommodate such a critical conversation," Harris spokesperson Lily Adams told multiple outlets. "As Harris has said, this is a climate crisis and is one of the most urgent reasons we need a new president."

The intrigue: Harris' reversal followed criticism from some climate activists, including the Sunrise Movement, over her initial decision against participating.

• It's still unclear whether Harris will have unveiled details about her plans ahead of the event. The campaign did not respond to inquiries.
