Then Trump called the coronavirus “their new hoax.”

Trump’s comments came as the White House has struggled to adequately respond to and contain the coronavirus’s increasingly sweeping path. At the rally — held here on the eve of the Democratic primary in South Carolina — he sought to manage Americans’ expectations about the White House’s ability to fight it.

By undermining the news reporting on the virus and by trying to hold liberals responsible for a potential public health crisis that has little to do with politics, Trump did what he often does best: He sought to deflect blame at a time when many Americans sought leadership and scientific facts.

After Trump had downplayed the risks of coronavirus, he reassured supporters that the White House was “magnificently organized” in fighting it. In fact, Trump’s administration spent the week jockeying among themselves to lead the response, while the stock market tumbled with losses not seen since the global financial crisis in 2008. White House officials and the president grew so concerned this week that Trump put Vice President Mike Pence in charge of the response effort, swapping out his beleaguered health secretary.

None of that came up on Friday night, as Trump trash-talked his Democratic opponents in 2020 and characterized the coronavirus as the latest issue touching on border security.

“Whether it is the virus that we're talking about or many other public health threats, the Democrat policy of open borders is a direct threat to the health and well-being of all Americans. Now, you see it with the coronavirus. You see it. You see it with the coronavirus. You see that. When you have this virus or any other virus or any other problem coming in, it's not the only thing that comes in through the border and we are setting records now at the border,” Trump said.

Earlier in the week, the Trump administration tried to allay Americans’ concerns about the virus by downplaying the coronavirus’s seriousness. Trump also congratulated himself for shutting down flights between the U.S. and China.

But by the end of the week, White House officials including the president had shifted to pushing back against anyone who expressed too much concern about the virus or its effect on the economy, repeatedly blaming the Democrats and the media for the growing concerns and the steep drop in the stock market amid the uncertainty.

“It’s the unknown, you know, they look at it, and they say how long will this last. I think they’re not very happy with the Democrat candidates when they see them, and I think that has an impact,” Trump said at the White House on Friday afternoon before traveling to the campaign rally.

Top White House officials kept up the same mantra all day Friday.

The director of the National Economic Council Larry Kudlow told reporters that “people should not overreact” — from investors to everyday Americans. "Given what we know factually, it looks to me like the market had gone too far,” Kudlow said.

Acting chief of staff Mick Mulvaney talked about the ongoing coverage of the coronavirus as an attempt by the media to politically damage the president during an election year.

Health officials, meanwhile, spent the last two days trying to determine how a California resident became infected with coronavirus and who else the patient may have exposed to it. This was the first potential case of coronavirus in the U.S. that had not been contracted from traveling abroad and potential sign it could spread throughout the U.S.

That wasn’t the message on Air Force One on the flight down to South Carolina, with the televisions turned to Fox News. In the bubble the president travels in, the TV headlines told the world the president had a “firm grasp” on the coronavirus and that Democrats tried to score “political points” on it.
