At least 51 officers with the Salt Lake City Police Department remain under quarantine ahead of Wednesday night’s vice presidential debate between Vice President Mike Pence and Sen. Kamala Harris.

Of those, at least 16 officers have tested positive for COVID-19, Detective Michael Ruff confirmed to Fox News Wednesday morning, adding that officers who may have been exposed to the coronavirus while going out on calls are placed under quarantine out of an abundance of caution. He said the department does its own contact tracing and officers placed under quarantine are administered a test, and if the result comes back negative, they return to the field.

Ruff said the Salt Lake City Police Department is one of several partner agencies operating in the city to prepare for the vice presidential debate hosted at the University of Utah’s Kingsbury Hall. Other agencies include University Police, the Unified Police Department of Greater Salt Lake, Utah State Police and Secret Service.

He said he does not expect the quarantine measures to threaten police operations regarding the debate because they’ve been preparing for this event for over a year and knew it would be labor-intensive before COVID-19 was recognized as a threat.

When fully staffed, Ruff said the department has roughly 570 officers – meaning about 9% are under quarantine. Ruff said whenever officers are taken out of the field, it does affect other operations to some degree, but there are some contingency plans involving shift changes in place and some officers in quarantine can still work by taking police reports over the phone.

The debate comes days after President Trump tested positive for COVID-19 early Friday and was briefly hospitalized over the weekend at Walter Reed National Military Medical Center before being released Monday to continue treatment at the White House.

The first family stirred up some controversy during the first presidential debate between Trump and Democratic nominee Joe Biden by taking their seats in the audience and removing their masks.
