Maya Angelou at home resting after hopitalization

(CBS/AP)Maya Angelou is recovering from a brief illness that forced her to cancel a planned speech in Texas.

The 83-year-old poet was set to speak on Wednesday but came down with an illness that left her in the hospital for three days, says her lecture agent David LaCamera.

LaCamera says Angelou is resting at home in Winston-Salem, N.C., and can't travel. He says her doctor told her that she's on the road a lot and has to cool it for a few days.

LaCamera declined to describe the nature of the illness that kept Angelou hospitalized until her release on Saturday.

Angelou had been scheduled to speak at Texas Women's University in Denton.
