A Maine manufacturer of COVID-19 testing swabs said it’s discarding the entire output created while President Donald Trump toured the plant without a mask, USA Today reported.

A representative of Puritan Medical Products did not say explicitly that the action was due to Trump’s lack of protective gear during his tour on Friday, but no other explanation was offered. The swabs are being tossed as manufacturers struggle to keep up with demand for the critical for COVID-19 testing components.

“The running of the factory machines ... will only occur when the president is touring the facility floor,” the company’s marketing manager, Virginia Temple, told the newspaper. “Swabs produced during that time will be discarded.”
