Former US vice presidential nominee Sarah Palin on Tuesday said her husband is still in the intensive care unit of an Alaska hospital with multiple injuries, including broken bones and a collapsed lung, two days after a serious snowmobile accident.Todd Palin, 51, suffered multiple broken ribs, a broken shoulder blade and clavicle, as well as knee and leg injuries. He was back in surgery to repair several fractures, Sarah Palin said in a statement on social media on Tuesday."Knowing Todd, once he's cognizant, he'll probably ask docs to duct tape him up and he'll call it good," she said. "He's tough."An attorney for Sarah Palin declined to comment. A representative for the hospital where Todd Palin is said to be receiving treatment could not be reached.
