(CNN) President Joe Biden on Wednesday announced a slate of acting agency heads after taking office without a single one of his Cabinet nominees in place and confirmed by the US Senate.
"These individuals, nearly all of whom are career civil servants, will temporarily lead federal agencies while Cabinet nominees continue moving through the confirmation process," White House officials said in a statement.
Later Wednesday evening, the Senate voted to confirm Biden's first Cabinet nominee. Avril Haines, who was a national security official in the Barack Obama administration, became the first woman to step into the role of director of national intelligence.
The Biden team had previously declined to publicly announce the officials who would take over departments in a temporary capacity because of concerns the Trump administration could attempt to thwart or complicate their work.
The Republican-led Senate, amid the coronavirus pandemic and heightened security around the US Capitol following the recent deadly riot, had been slower to schedule confirmation hearings for Biden's nominees than it has for previous presidents. Five of Biden's national security Cabinet nominees, including Haines, faced Senate panels on Tuesday as part of the first step in the confirmation process.
Biden said Wednesday that he was not concerned that key nominees hadn't yet been confirmed.
"I'm confident we can move quickly," the President told reporters at the White House.
Vice President Kamala Harris on Wednesday swore in three new Democratic senators on Wednesday afternoon, which officially gave Democrats control of the Senate and could accelerate the confirmation timeline. Democrats will now be able to confirm Biden's nominees without Republican support.
