Joe Biden promised his cabinet would be diverse and it looks like he is following through on that vow. The president-elect announced these picks today and will discuss the nominations during an event tomorrow.

The New York Times reports:

At an event in Wilmington, Del., Mr. Biden will announce plans to nominate Alejandro Mayorkas to be his secretary of the Department of Homeland Security, his transition office said, and Avril Haines to be his director of national intelligence. He intends to name Mr. Kerry as a special presidential envoy on climate. The transition office also confirmed reports on Sunday night that Mr. Biden will nominate Antony J. Blinken to be secretary of state and Jake Sullivan as national security adviser.

In announcing his choices, Biden wrote:

“We have no time to lose when it comes to our national security and foreign policy. I need a team ready on Day 1 to help me reclaim America’s seat at the head of the table, rally the world to meet the biggest challenges we face, and advance our security, prosperity, and values. This is the crux of that team.

These individuals are equally as experienced and crisis-tested as they are innovative and imaginative. Their accomplishments in diplomacy are unmatched, but they also reflect the idea that we cannot meet the profound challenges of this new moment with old thinking and unchanged habits — or without diversity of background and perspective. It’s why I’ve selected them.”

Monday afternoon The Wall Street Journal also broke news that “Joe Biden plans to nominate former Federal Reserve Chairwoman Janet Yellen, an economist at the forefront of policy-making for three decades, to become the next Treasury secretary, according to people familiar with the decision.”

Yellen would be the first woman to hold the position.

Several of Biden’s nominees are taking to Twitter today to react.
