An outdoor speech at the first rally by US President Donald Trump since the coronavirus outbreak was abandoned on Saturday in Tulsa, Oklahoma.
The US Vice-President Mike Pence was set to address crowds, however it is believed low numbers caused the last-minute cancellation.
The US is still struggling to contain COVID-19 - which Mr Trump described as "Chinese kung flu" during the rally.
Just hours earlier, it had been revealed that six members of Mr Trump's campaign team had tested positive for coronavirus.
Those in attendance were even asked to waive their rights to sue the Trump campaign, should they catch the virus.
At least 10,040 people have tested positive in Oklahoma and 368 people have died.
Mr Trump also told the crowd that he had "saved hundreds and thousands of lives" by closing the US off to flights from China at the end of January.
He went on to describe testing for the coronavirus as a "double-edged sword" - saying that 25 million people had been tested in the US but "when you do testing to that extent, you're going to find more people, you're going to find more cases, so I said to my people 'slow the testing down please'."

Gina London is a former CNN Washington correspondent.
She told Newstalk Breakfast: "It's amazing the number of things that this administration declares are sarcasm or joking or whatever - 'fake news' - when it doesn't come out the way [it wants].
"He hasn't had one of these [rallies] since March 2nd when everything was shut down.
"And in the wake of one, two, three record days of cases of COVID-19 - or 'kung flu' as he inexplicably called it, amidst the backdrop of all these demonstrations for social justice and racial equality.
"'Oh, it's a joke' - it's not a joke.
"There were three record numbers of cases of COVID in Tulsa, in the very city, that he actually had to have the Supreme Court of Oklahoma actually ruled that they wouldn't enforce the social distancing or mask coverings for faces during this thing.
"There were a group of businesses that came out and said 'this is a super-spreader event'".
"There's 19,000 seats that could have been in that arena filled, and earlier before the event the administration was saying they had a million people that registered for it and that there wouldn't be an empty seat.
"There were empty seats - but make no mistake, there were thousands of people gathered indoors."
"Some of them wore masks to be fair, most did not - and certainly the president did not as he went off in his signiture wheeling style".
"There was supposed to be an outdoor speech from [US Vice-President] Mike Pence, in fact, outside the rally.
"But there were few, few, few people - the reports showed - that actually were remaining outside as everybody made their way in.
"My speculation, and his speculation, was that there frankly weren't enough people to call for outdoors.
"The organisers of the Trump team were dismantling the stages that had been set outside.
"My estimation is there just wasn't enough people to warrant it".

"The White House claims they weren't involved in the set-up there... that they're now in quarantine.
"But this disease is not over".
During his speech, Mr Trump also claimed that "the silent majority is stronger than ever before".
But it appeared that many of his "silent majority" had stayed at home, amid warnings from health officials about the risk of spreading the coronavirus.
The stadium has a capacity of 19,000 but organisers had said only 10,000 people would be allowed to enter.
The rally at the BOK stadium in Tulsa, Oklahoma, had been promoted as a comeback opportunity for Mr Trump - a chance to boost his campaign for re-election in November.
He is currently behind Democratic rival Joe Biden in many polls.
But in the hours before Mr Trump started speaking, crowds appeared to be significantly lighter than expected and campaign officials scrapped plans for him to first address an overflow space.
Mr Trump blamed the news media for saying "don't go, don't come, don't do anything", adding: "We begin our campaign... the silent majority is stronger than ever before."
He also blamed a group of Black Lives Matter protesters outside, a group also smaller than expected but largely peaceful, described by him as "the unhinged left-wing mob".
