Susan Rice, President Joe Biden's top domestic policy adviser, is departing her post.

In a statement acknowledging Rice's exit, Biden remembered how he "surprised" pundits by tapping Rice for the position overseeing domestic affairs since she is "synonymous" with foreign policy, having previously been former President Barack Obama's national security adviser and ambassador to the United Nations.

"But what I knew then and what we all know now — after more than two years of her steady leadership of the Domestic Policy Council — it’s clear: there is no one more capable, and more determined to get important things done for the American people than Susan Rice," Biden wrote.

"As the only person to serve as both national security adviser and domestic policy adviser, Susan's record of public service makes history," he said. "But what sets her apart as a leader and colleague is the seriousness with which she takes her role and the urgency and tenacity she brings, her bias towards action and results, and the integrity, humility and humor with which she does this work."
