Sen. Harris Suspends Campaign Travel, Staffer Tests Positive For Virus

Emhoff and Harris have canceled their campaign travel until Monday due to COVID-19 cases among campaign staff. Two individuals tested positive after a recent trip, and a third case was linked to Biden's campaign. Despite these cases, Biden does not need to quarantine as per medical advice. Both Biden and Harris have tested negative multiple times. Harris was not in close contact with the infected individuals, but her travel is canceled as a precaution. She will continue virtual campaigning.
