Gov. Kathleen Sebelius ordered Friday that all Kansas flags be lowered to half-staff Sunday to honor former first lady Lady Bird Johnson.

“I urge all Kansans to join me in honoring Lady Bird Johnson’s memory,” Sebelius said in a statement. “She was a graceful first lady for our nation who distinguished herself through her commitment to conservation and her work to protect the environment.”

Johnson died Wednesday at age 94 in Austin, Texas. She will be buried at a family ranch there Sunday.
