Clark Hill’s Chicago office is still open following news that a person who works in the same building complex as the firm tested positive for COVID-19, the firm said in a statement.

Chicago news outlets on Wednesday reported that an employee for a commercial real estate developer was diagnosed with the coronavirus Tuesday. The employee works in One Prudential Plaza, the same tower Clark Hill has 110 lawyers and support staff. CA Ventures, the real estate developer, told the Chicago Tribune the employee hadn’t been in the office since March 3.
