Rep. Edmund Kuempel, R-Seguin, is now out of a medically induced coma and his body temperature has been raised to normal, said his friend Rep. Charlie Geren, R-Fort Worth.
"I saw him last night, and he looked a whole lot better than he did when he left here," Geren said.
Kuempel collapsed late Tuesday and was discovered by a House sergeant at arms. He was revived by a legislator who is a doctor and by Texas Department of Public Safety officers.
On Friday, Kuempel moved his foot, attempted to respond to his son's and daughter's voices, and opened his eyes, Geren told House members.
"It was exciting. The family, as you can imagine, is very, very excited," he said.
