The journalist took to Instagram on Wednesday to pay tribute to her former partner, who died 20 years ago at age 42 from colon cancer.
Couric shared a heartwarming photo of Monahan posing with one of their two children, daughters Ellie, now 26, and Caroline, 22. "Jay Monahan," she captioned it. "January 9, 1956-January 24, 1998. Twenty years ago today. We miss you."
The 61-year-old author has been an advocate for colon cancer awareness ever since the death of her husband. Couric, who also lost her sister, Emily, to pancreatic cancer in 2001, famously underwent a colonoscopy on-air in March 2000, and then a mammogram in 2005, in hopes of raising awareness about cancer prevention.
