Leaders of a megachurch in Phoenix installed air-purifying machines that they claimed ‘kill 99.9% of Covid-19 within ten minutes’ before hosting Donald Trump’s campaign rally on 23 June. They then backtracked shortly before he spoke, causing confusion Senior pastor Barnett said the alleged virus-killing technology, developed by members of their church, ‘ionised the air’ by ‘taking particulates out’ to create a pandemic-free atmosphere. Potential Trump supporters were told, ‘When you come into our auditorium, 99% of Covid is gone, you'll be safe and protected. Thank God for great technology.’ A university professor said the ‘technology’ was not going to do anything to protect people in that space: ‘We’re in the midst of a serious pandemic and health situation; the last thing people need is false information about air cleaning technology.’ May God’s hand direct scientists and academics to end the pandemic with a successful vaccine.
