DES MOINES, Iowa - A sixth person working at the Iowa Capitol is positive for COVID-19.
The House Chief Clerk confirmed in an email to lawmakers the person tested positive Monday, and was most recently in the building last Tuesday.
The person was reported to have worn a face mask at all times.
The first COVID-19 case at the Capitol was reported just four days after the legislative session began last month.
Democratic State Representative Amy Nielson of North Liberty became the first known state lawmaker to be infected with the virus in late January,
Republicans, who control the legislature, have encouraged but not required face masks be work at the Capitol.
A group of unions representing state workers have filed a complaint with the Iowa Occupational Safety and Health Administration (OSHA), saying the lack of a mask mandate threatens the safety of everyone who enters the building.
There's also no requirement for people working at the capitol to reveal positive COVID cases.
