(CNN) -- Garrison Keillor, author and host of the folksy radio show "A Prairie Home Companion," was being treated Wednesday for a minor stroke he suffered over the weekend, a hospital spokesman said.

Keillor, who turned 67 last month, was admitted to St. Mary's Hospital at the Mayo Clinic in Rochester, Minnesota, on Sunday night, spokesman Karl Oestreich said in a news release.



"He is up and moving around, speaking sensibly, working at a laptop, and it's expected he'll be released on Friday," Oestreich said.



"He plans to resume a normal schedule next week."



The live variety show "A Prairie Home Companion" is aired on Minnesota Public Radio.



Keillor launched the program on July 6, 1974, in a St. Paul, Minnesota, college theater before an audience of 12 people.



According to a "Backstage Chat" on the show, Keillor got the idea for it from watching the Grand Ole Opry.



Keillor, also a storyteller and satirist, has written 11 books, including three for children. He was inducted into the Radio Hall of Fame in 1994.
