Sen. Bernie Sanders (I-Vt.) and former Vice President Joe Biden have canceled Ohio rallies due to the coronavirus outbreak, their campaigns announced Tuesday.

These are the first campaign events in the 2020 presidential election cycle to be canceled because of the virus.

We are heeding the public warnings from Ohio state officials, who have communicated concern about holding large, indoor events during the coronavirus outbreak, the Sanders campaign said in a statement about the rally in Cleveland that was scheduled to take place Tuesday night. Sen. Sanders would like to express his regret to the thousands of Ohioans who had planned to attend the event tonight.

Bidens campaign spokesperson released a similar statement soon after, saying Bidens event was being canceled out of an abundance of caution.

Both campaigns said all future events would be scheduled on a case by case basis, depending on guidance from public health officials.
