CHICAGO (CBS) — A member of Illinois House Speaker Emanuel “Chris” Welch’s staff tested positive for COVID-19 on Monday, as lawmakers and their staffs returned to Springfield after their two-week spring break.

The staffer tested positive on Monday as part of the required testing protocols for returning to work at the Illinois State Capitol, according to Jaclyn Driscoll, spokeswoman for the speaker’s office. The staffer will quarantine for 14 days.

“Contact tracing was performed, and those who were in contact with the staff member are now quarantining, pending negative tests,” Driscoll said in an email. “The Speaker was not in contact with the staff member and continues to stress the vital importance of public health safety measures as the House of Representatives gets back to work for the people of Illinois. Thanks to the implementation of the U of I Shield testing, the Speaker’s Office was able to catch the positive result prior to the start of session today and it remains a requirement for all staff to be tested regularly.”

Driscoll said nine other staff members who shared office space with the worker who tested positive will be working remotely pending a negative test result.
