In the wake of the devastation of Hurricane Helene in the United States this week, a new storm emerged on social media - false rumors about how disaster funds have been used, and even claims that officials control the weather.

Local and national government officials say they are trying to combat the rumors, including one spread by Republican presidential candidate Donald Trump.

One of the more far-fetched rumors is that Helene was an engineered storm to allow corporations to mine regional lithium deposits. Others accuse the administration of President Joe Biden of using federal disaster funds to help migrants in the country illegally, or suggest officials are deliberately abandoning bodies in the cleanup.

Republican Congress member Marjorie Taylor Greene posted on X Thursday night: "Yes they can control the weather. It's ridiculous for anyone to lie and say it can't be done."

The conspiracy theories come at a pivotal time for rescue and recovery efforts following the storm, one of the deadliest U.S. hurricanes this century. And the presidential election between Trump and Vice President Kamala Harris is just over a month away.

Republicans and Democrats alike say the rumors are causing problems.

"I just talked to one Senator that has had 15 calls TODAY about why we don't stop ........ 'fill in the blank,'" said Kevin Corbin, a Republican in the North Carolina Senate - a state that is one of the hardest hit by Helene. "98 percent chance it's not true and if it is a problem, somebody is aware and on it," he wrote on Facebook.

"I'm growing a bit weary of intentional distractions," he added.

White House officials on Friday accused some Republican leaders and conservative media of intentionally peddling rumors to divide Americans in a way that could harm disaster relief efforts.

"Disinformation of this kind can discourage people from seeking critical assistance when they need it most," a White House memo said. "It is paramount that every leader, whatever their political beliefs, stops spreading this poison."

The memo highlighted a claim by Trump during a rally this week that Biden and Harris had used federal emergency funds "on people that should not be in our country."

"This is FALSE," the memo said. "No disaster relief funding at all was used to support migrants housing and services. None. At. All."

In response to a request for comment for this article, the Trump campaign repeated accusations that FEMA funds had been spent on housing migrants in the country illegally.

The Federal Emergency Management Agency has the funds for immediate response and recovery efforts for Helene, the White House memo said, and has provided millions of dollars in relief to those recovering.

FEMA has been the target of so many falsehoods it has set up a rumor response page on its website to try to tamp them down.

Helene slammed into Florida a week ago and has killed over 200 people and devastated a half dozen states in the U.S. Southeast.

Some officials are trying to combat the disinformation themselves on social media. Katie Keaotamai, who works at FEMA but said she was speaking on social media in a personal capacity, explained FEMA's disaster response processes in several TikTok posts with thousands of views.

Disaster events are often politicized, said Kate Starbird, co-founder of the Center for an Informed Public at the University of Washington, adding that social media rewards "sensationalism and outrage with attention."

"Manipulating the sensemaking process (e.g. spreading conspiracy theories and disinformation) and politicizing the event will both make it harder to respond and recover now — and to make informed decisions about how to prepare for and mitigate the next one," Starbird said.
