• Trump demands an apology from Biden and Harris after "reckless anti-vaccine rhetoric"
  • The president renewed promises to deliver a vaccine "very soon"
  • Biden and Harris said they would consult scientists before taking a potential vaccine

President Donald Trump slammed former vice president Joe Biden and Democratic vice-presidential candidate Kamala Harris hours after they questioned how much the White House occupant could be trusted when it comes to delivering an effective coronavirus vaccine. 

Speaking at a news conference in Washington, D.C., the president demanded both candidates apologize for their "reckless anti-vaccine rhetoric" that could be "endangering lives and it undermines science."

"What's happening is all of the sudden you'll have this incredible vaccine, and because of that fake rhetoric — it's a political rhetoric, that's all it is, just for politics," he added.

Trump also renewed his pledge to produce a vaccine in a very short period of time. “The vaccine will be very safe and very effective, and it will be delivered very soon,” he said, noted NBC News

The U.S. president’s statement comes after Biden and Harris warned Americans to be skeptical of news coming from Trump about a potential coronavirus vaccine. 

During a Labor Day event in Lancaster, Pa., reporters asked Biden whether he would accept if the Trump administration offered him a coronavirus vaccine a day before the November elections.  

While he did not voice out a rejection, Biden insisted on full transparency from the administration on potential vaccines. He also said he would likely consult scientists, adding he was worried that people might not take an effective vaccine because the president is “undermining public confidence” in the process. 

In an exclusive interview with CNN’s “State of the Union” on Sunday, Harris was asked if she would be willing to take a vaccine if the government distributed it one day prior to the election. 

The Democratic vice-presidential candidate said she would not take the word of the president on the effectiveness and safety of the potential COVID-19 vaccine.

"I will say that I would not trust Donald Trump, and it would have to be a credible source of information that talks about the efficacy and the reliability of whatever he's talking about," she told host, Dana Bash. 

To date, Johns Hopkins University data reported close to 6.3 million confirmed coronavirus cases and nearly 190,000 deaths in the U.S., which still has the highest number of cases and deaths of any country across the globe. 

Public health officials have raised concerns that gatherings over the Labor Day holiday could cause another spike in COVID-19 cases.
