John Kerry In, Elizabeth Warren Out Of Joe Biden Administration

MASSACHUSETTS — President-elect Joe Biden's administration will have a one-time U.S. senator from Massachusetts, but it doesn't appear to be Elizabeth Warren.

Biden's transition team announced Monday it tapped former U.S. Sen. and Secretary of State John Kerry to be the top climate official in his administration.

Reports later in the afternoon revealed Biden picked former Federal Reserve Chair Janet Yellen as Treasury secretary, the position Warren had reportedly been jockeying for.

Warren, 71, threw her support behind Biden after she withdrew from the Democratic primary in March. Warren had reportedly become a close adviser of Biden's on economic policy.

Progressives wanted Warren to bring her plans for structural change to Washington, but Biden instead went with someone considered a safer pick to be confirmed by Senate Republicans.

Kerry, 67, will be the special presidential envoy for climate. The position doesn't require Senate confirmation. He'll also sit on the National Security Council, bringing a focus on climate change.

Kerry had a hand in the Paris Climate Agreement, providing the United States' signature in 2016. Biden has said he'll rejoin the Paris Climate Agreement when he takes office.

"The work we began with the Paris Agreement is far from done," Kerry tweeted Monday afternoon." I'm returning to government to get America back on track to address the biggest challenge of this generation and those that will follow. The climate crisis demands nothing less than all hands on deck."

Kerry served Massachusetts as U.S. senator from 1985-2013. He left office to become President Obama's secretary of state.
