Maryland Speaker of the House Michael Busch has undergone a liver transplant.
The speaker's office said in a statement that the 70-year-old Busch had the procedure Thursday at the University of Maryland Medical Center.
Busch's sister provided the donation.
The speaker's office says Busch was recently diagnosed with nonalcoholic steatohepatitis.
Busch said his health had gotten worse in recent weeks. "As many of you have likely noticed, my energy level did not return after a brief hospitalization last fall,” he said in a statement. “Over the past several months, a medical team from University of Maryland Medical System has been working to determine why my energy level did not bounce back,” he said.
Busch says his doctors expect recovery will take seven weeks. His adult daughters will spend the next few months at home with him and his wife.
Busch, a Democrat, is the longest serving speaker in Maryland history.
