Confirming here that Henry Waxman was admitted yesterday to Cedars-Sinai. His committee spokeswoman in Washington says he "felt unwell" and was "admitted for routine testing."
Waxman remains as a patient at the hospital, but "is feeling much better now," says spokeswoman Karen Lightfoot.
When last seen in Washington, Waxman managed the energy bill through the House for that close vote late last Friday. As chairman of the powerful Energy and Commerce committee, he has jurisdiction over both the energy bill and the health care bill.
Waxman ousted fellow Democrat John Dingell, the longest serving member of the House in American history, as chair of the committee last January.
