As family gathered at Sandord Health in Bismarck, Isaac Cramer, the son of Rep. Kevin Cramer, R-N.D., saw some stabilization and slight improvement over the weekend.

"His hemoglobin has stabilized without blood transfusions since very early Sunday morning," said Kevin Cramer, updating his 35-year-old son's condition, which involved kidney and liver failure due to an ongoing battle with alcoholism.

"He has been off of blood pressure assistance for 24 hours and has maintained good pressure on his own. His heart rate has also improved as they’ve reduced sedation. His kidneys are improving and his temperature is down slightly. He remains critical, but instead of planning for the worst, we are planning for recovery," Kevin Cramer said.

Neither friends of the family nor Rep. Cramer have publicly described the events that led to Isaac Cramer’s hospitalization.

“Words cannot begin to express our family’s appreciation for all of the support we are receiving from around the country,” Cramer wrote on Facebook. “To the many prayer warriors who are holding us up, be encouraged. We feel it, and so does Isaac Cramer.”

Kevin and his wife Kris Cramer’s other children are another adult son, Ian; adult daughters, Rachel and Annie, and an 11-year-old adopted son, Abel. They also have four grandchildren.

Cramer recently announced his plans to launch a U.S. Senate campaign to unseat Democratic incumbent Heidi Heitkamp in this fall’s general election.
