MSU Faculty members say the decision to appoint Engler was rushed and several members of the student body agree.
The interim president of Michigan State University has instructed faculty and other school employees to cooperate with investigations of sexual abuse.
Engler said "no internal candidates will be considered" for the job.
Engler was approved by the board on Wednesday after longtime president Lou Anna K. Simon resigned amid mounting pressure from lawmakers, students, and several board members for MSU's handling of the Larry Nassar scandal.
Desite that, Beekman is ready to take on his new job.
"I am honored to receive this appointment and look forward to this new challenge", Beekman said.
Former MSU Athletic Director Mark Hollis made what he said was a retirement announced on January 26. "This is obviously a new day at MSU and I am pleased to be part of the changes".
Michigan State has been without an athletic director since February 1.
The letter also called for the board to use faculty input in quickly hiring someone with an academic background to be Michigan State's permanent president. What more needs to be done?
