WASHINGTON – A group of anti-Trump conservatives released a new ad Thursday targeting President Donald Trump on his messaging over the coronavirus outbreak.

As cases have skyrocketed around the country, the White House's messaging toward the virus has dramatically shifted from saying they had already "shut it down" in regard to the spread of COVID-19, to daily press briefings addressing the growing number of cases.

The ad from the Republicans for the Rule of Law, who backed the president’s impeachment, shows Trump speaking about the issue in January, when there was just one confirmed case. Trump said then he was not at all concerned about a pandemic striking the U.S.

The video moves through a timeline of the morphing messaging from Trump and members of his administration on the coronavirus as cases in the U.S. dramatically increased.

The ad highlights the president, speaking to a gathering of African-American leaders in late February at the White House, claimed the virus was going "to disappear. One day – it's like a miracle." It also notes when he falsely underplayed the amount of time required to develop a vaccine.

Chris Truax, a spokesman for the Republicans for the Rule of Law, released a statement saying, "In a crisis, there are three rules that must be followed when communicating with the public: Be first. Be right. Be credible. President Trump has often been first but he has seldom been right and he has never been credible."

"President Trump bears responsibility for misleading his supporters," the statement said.

The video includes a moment at the beginning of March when Trump dismissed a reporter by saying "That's CNN – fake news!" when asked if his administration was taking the disease seriously. Cases had surged then to 262.

The video shows Trump saying on March 15, when the number of cases had grown to nearly 3,500, that the virus was “something that we have tremendous control over,” though noting it was extremely contagious.

On March 17, Trump said he'd "rate it a 10" when asked about his response to the pandemic.

"I thought it was a pandemic long before it was called a pandemic," he said, contradicting earlier claims.

"Accurate and timely information is America’s most potent defense against the pandemic we now face," Truax continued, saying the majority of "Republicans who have been misled by the president’s self-serving coronavirus lies are our families, our friends, and our neighbors."

"We urge them, and all Americans, to get their coronavirus information from the CDC and other reliable sources. This isn’t about politics. It’s about saving hundreds of thousands of American lives," he said.

Cases of COVID-19 had exceed 13,000 in the United States by Thursday night.
