Nancy Pelosi has said she is “heartbroken and traumatised” by the violent attack on her husband.
The US House of Representatives speaker said her family was “grateful for the quick response of law enforcement” and for his medical care.
Paul Pelosi was struck with a hammer by a male assailant at the couple’s San Francisco home on Friday.
The 82-year-old’s condition “continues to improve” after the attack, Mrs Pelosi said.
He suffered a fractured skull and injuries to his right arm and hands, and remains in hospital receiving “life-saving” care, she said.
