Cartoonist, author and political commentator Scott Adams died Tuesday after a battle with prostate cancer. He was 68. His ex-wife and caregiver, Shelly, made the announcement on Adams’ livestream Tuesday morning.

"If you are reading this, things did not go well for me," Adams' X account said on Jan. 13. The cartoonist had documented his illness for many months.

"If you got any benefits from my work, I'm asking you to pay it forward as best you can," Adams wrote. "That is the legacy I want."
