According to the source, Miller has been tested for coronavirus but the results are not back.
Miller is Deputy Commissioner for Counterterrorism and Intelligence and a former ABC News correspondent.
If Miller tests positive, he would become the third NYPD chief to test positive for COVID-19.
Both NYPD Chief of Transit Edward Delatorre and NYPD Deputy Commissioner for Employee Relations Robert Ganley are recovering after testing positive for the virus.
In addition to Miller, a source with knowledge says close to two dozen members of the Joint Terrorism Taskforce are out sick, due to either confirmed or presumed cases of COVID-19.
According to the source, some of those members are already mostly recovered and will be back to work soon.
