DAVIS, Calif. — 6:13 p.m. update:
The Theta Chi Fraternity president is speaking out after UC Davis officials announced a member of the organization tested positive for the coronavirus.
Theta Chi Fraternity President Grant Hoffman tells ABC10 a gathering didn't take place and he is shocked at the allegations.
Hoffman said the fraternity could appeal the university's allegations at a hearing on Monday.

Officials said the party violates both the university's and county's quarantine guidelines. Professional cleaners were hired to have clean the house.
There are 10 students who live in the Theta Chi Fraternity house, which is off-campus. Nine students were ordered to move into quarantine designated apartments on campus the following day.
One student is completing his quarantine at the fraternity house so that he could take care of the pets. It is not clear if the student tested positive lives in the fraternity house.
Yolo County Public Health Chancellor Gary S. May said he is disappointed in learning the students violating health guidelines.
"I urge everyone in our community to follow public health guidelines and mandates," May said. "Including wearing face coverings, socially distancing from one another and washing your hands frequently."
