The White House moved Saturday to quash claims that government officials control the weather, including a far-fetched rumor circulating on social media that Hurricane Helene was an engineered storm to allow corporations to mine regional lithium deposits.
“We have seen a large increase in false information circulating online related to the federal response to Hurricane Helene,” a statement said, pointing to a “number of scam artists, bad-faith actors, and others who want to sow chaos because they think it helps their political interests are promoting disinformation about the recovery effort.”
The White House said the rumors, which include claims that emergency disaster money had been spent housing immigrants and that relief funds would be limited to $750 per claim, were “wrong, dangerous” and said “it must stop immediately”.
The warning, which speaks to the intense political environment Helene figuratively crashed into, came hours after Biden told lawmakers to refill the coffers of disaster relief programs as the projected recovery and rebuilding costs related to Hurricane Helene are estimated to be as much as $200bn over 10 years.
In a letter sent to congressional leaders, the president said while the Federal Emergency Management Agency (Fema) and the Department of Defense are able to meet “critical life-saving and life-sustaining missions and will continue to do so within present funding levels”, they will need additional funding.
“My administration has provided robust and well-coordinated federal support for the ongoing response and recovery efforts,” Biden wrote.
“As with other catastrophic disasters, it will take some time to assess the full requirements for response and recovery efforts, and I fully expect that the Congress will do its part to provide the funding needed.”
Biden said that a comprehensive disaster relief package would be necessary when Congress returns on 12 November – but said action on individual programs could be needed before then. But there are currently no plans for Congress to reconvene before the election.

The request comes as Kamala Harris cut short a campaign swing through the western states to visit western North Carolina in the southern Appalachian mountains where entire towns were washed away.
Biden viewed the damage and cleanup efforts in the Carolinas by air on Wednesday, and again in Florida and Georgia on Thursday. He said the work to rebuild will cost “billions of dollars” and additional disaster relief funding “can’t wait … people need help now”.
At least 225 people have been confirmed dead from Helene, and officials say they expect the death toll to continue to rise as recovery efforts continue. A police department spokesperson in Asheville, North Carolina, told CBS News in an email late on Friday that it is “actively working 75 cases of missing persons”. Nearly 1 million people remain without power.
In his letter to lawmakers, Biden said that funding through the Small Business Administration (SBA) “will run out of funding in a matter of weeks and well before the Congress is planning to reconvene”.
The SBA is designed to help small business owners and homeowners recoup property and equipment through the disaster relief loan program. Administration officials told CNN that the program needs $1.6bn in additional funding to meet about 3,000 Hurricane Helene-related applications it is receiving daily.
Last month, before Helene hit, the White House warned that the low funding levels could lead to the SBA “effectively ceasing operations” after paying out for weather-related costs and accidents, including the Key Bridge collapse in Baltimore, the continued recovery after Maui’s wildfires and tornado damage in the midwest.
The damage caused by Helene could cost upwards of $34bn, according to early estimates from Moody’s Analytics. The private forecaster AccuWeather put the cost of damages at $225bn to $250bn, with very little covered by private insurance.
The issue of Helene costs is already deeply political. The Republican House speaker, Mike Johnson, has said lawmakers would assess the post-Helene needs in full after the election.
Former president Trump has accused Democrats of spending over $640m in Fema funds on housing migrants, a claim the White House calls “bold-faced lies”.
On Friday, in Georgia, Trump said: “A lot of the money that was supposed to go to Georgia and supposed to go to North Carolina and all of the others is going and has gone already.
“It’s been gone for people that came into the country illegally, and nobody has ever seen anything like that. That’s a shame.”
Officials say those funds, authorized by Congress, was part of an entirely different program run by Fema unconnected to disaster relief but to provide housing to immigrants applying for US citizenship.
The disaster agency responded to Trump’s claim with a fact-check page. “This is false,” Fema said in a statement. “No money is being diverted from disaster response needs.” A week after the hurricane hit, more than $45m has been dispersed to communities affected by the storm.
