President Trump issued an executive order on Monday that restricts federal funding for research, which involves a controversial scientific research field called “functional rewards” research.

The study, also known as the "dual use" study, involves experimenting with viruses and other pathogens that have the potential to trigger the pandemic. These studies may find that infectious drugs may become more transmissible or make people sick.

The field has long been controversial because of concerns that scientists will create more dangerous pathogens in their labs that could emerge and cause a pandemic. Over the years, these concerns have led to many efforts to monitor and control the study more strictly.

But research on dysfunction caused particular controversy and political polarization during the 19th pandemic. A theory that the pandemic began said that the SARS-COV2 virus that caused COVID-19 spilled out from a Chinese government laboratory in Wuhan, China.

"Many believe that dysfunction research is one of the main reasons that has caused our shocking homosexual pandemic in the past decade," White House Secretary Will Scharf said. "The executive order first does something, it provides powerful new tools to enforce a ban on federal funding for functional rewards research abroad. It also strengthens other mechanisms of negligence related to the issue and creates an oversized strategy to ensure that biomedical research is being conducted safely."

Many scientists have refuted this theory, saying the weight of evidence suggests that the pandemic began when someone in China was infected by wild animals carrying the virus.

That said, many scientists agree that better supervision is needed because of the possible risks. But many fear that the suspension will be too broad and may kill security research, which is necessary to prevent or respond to the next pandemic.

"If we ban it, next time we come to the co-virus again, we won't have data to quickly find new treatments, screenings or even preventive measures," said Kristin Matthews, a science and technology policy researcher at the Baker Institute for Public Policy at Rice University.

But others want to limit the funds.

"If one of these pathogens is released by accident, or intentionally, they can cause a pandemic," said Richard Ebright, a microbiologist at Rutgers University.

According to the White House, the executive order will prevent the U.S. from providing funding for functional rewards for research in the United States “focusing countries” (such as those of China and Iran) and other foreign countries “deemed not to have sufficient research oversight.” The order also bans the dollar from "contributing to foreign research that could cause another pandemic."

The order also "gives U.S. research institutions federal funding and ends federal funding, which could pose a threat to U.S. public health, public safety, or national security, according to a fact sheet from the White House."

The White House said the order would “improve the safety and security of biological research without hindering our innovation.”

The White House also issued statements from several Trump administration officials who believe the funding restrictions are necessary.

"I praise President Trump for his courage and vision," said Robert F. Kennedy Jr., Secretary of Health and Human Services.

"It's a historic day," said Dr. Jay Bhattacharya, director of the National Institutes of Health. "The behavior of this study does not protect us from the pandemic, and as some may say, it does not protect us from other countries. There are always dangers when this study is conducted, and it may even leak out by chance and even cause a pandemic."

"It's crazy, thinking that the whole nightmare may be the result of some scientists' confusion with nature in technology," said Dr. Marty Makary, a specialist at the Food and Drug Administration.
