Attorney General Eric Holder was released from the hospital Thursday afternoon and is "resting comfortably" at home after a morning health scare, the Justice Department said.
Holder was taken to the hospital after falling ill during a morning meeting with senior staff at the Justice Department.
Holder arrived at the hospital at around 10:30 a.m. and was "treated for an elevated heart rate," Fallon said.
"He received medication that quickly restored his heart rate to a normal level, and after successfully completing a full range of tests, doctors were satisfied that the Attorney General could be discharged."
The spokesman said Holder had experienced the symptoms before, though in a milder form, and left the hospital under his own power in the early afternoon.
“Throughout today, the Attorney General has remained alert and in good spirits. He appreciates the well wishes from so many friends and colleagues, and is grateful for the excellent care he received from the professionals at MedStar Washington Hospital Center,” Fallon said.
White House press secretary Jay Carney said President Obama was aware of Holder's hospitalization.
"The president was notified and, of course, wishes him a speedy recovery," Carney said.
Holder, 63, has been the source of retirement speculation since a report in The New Yorker earlier this month suggested he might step down this year.
But Fallon told The Hill earlier this month that Holder simply meant he had a lot of work left that he hoped to accomplish in the coming year.
“The most the attorney general has said is that he still has a lot he wants to accomplish on issues like criminal justice reform, voting rights and LGBT equality. He did not speak about his plans any further than that,” Fallon said.
