Biden and Sanders vow joint climate work as part of endorsement

• Biden already rolled out changes to his health care and student debt policies last week designed to appeal to Sanders' backers.

Driving the news: The two men said they would form task forces on climate, health care, criminal justice, immigration, the economy and education.

• Axios' Alexi McCammond writes that it's a sign of Biden's continued outreach to the progressive wing of the party.

What we don't know: Who will be on the climate task force, but I'll write more when I know something.

• “They will be comprised of policy experts and leaders that represent the diverse viewpoints of the Democratic party,” a Biden campaign aide tells me.
• “The groups will work together to identify shared policy goals that build upon Vice President Biden’s progressive vision for America,” the aide said.
