Jim Harbaugh and Michigan athletic director Warde Manuel issued a joint statement on Saturday following Shemy Schembechler’s resignation from the program saying Michigan’s athletic department is “fully committed” to creating an environment where everyone feels “welcome.”

Schembechler, son of longtime U-M coach Bo Schembechler, was hired on Wednesday as an assistant director of football recruiting. On Saturday, he resigned from that position after his social media activity came under intense scrutiny.

Over the last 48 hours, Schembechler’s Twitter likes had been scrubbed to remove more than 1,000 likes on comments that were deemed offensive. Among them were tweets appearing to support slavery and Jim Crowe segregation. His Twitter account was eventually deleted altogether.

“We are aware of some comments and likes on social media that have caused concern and pain for individuals in our community,” Harbaugh and Manuel said in a statement, per The Athletic’s Austin Meek. “Michigan Athletics is fully committed to a place where our coaches, staff, and student-athletes feel welcome.”

Prior to Saturday’s statement, his name had appeared on the Michigan Athletics directory listing him as an Administrative Specialist.

Before coming to U-M, Schembechler was a scout in the NFL.
