> Hu submitted a letter to the university in 2016 disclosing his collaboration with a researcher [...] in Hefei, China.
> A university employee requested that Hu remove the letter from the application because it would violate an assurance document the university was submitting stating that the proposal had no restricted ties to China, the court documents say. A 2011 US law prohibits NASA from funding collaborations with China or Chinese businesses.
So (allegedly) the "university employee" told Hu to cover up potential illegal behavior by the university, or to protect the university from its belief that the government would mis-apply the law about "restricted ties".
