Home chemist flies to Yemen, gets arrested

Via the Department of Justice: 

Department of Energy Employee Arrested in Washington State on Charges of Attempted Material Support to Houthis

...According to court records, Ellaboudy, who was a Department of Energy employee, came to the attention of the FBI after they received information that he had purchased precursor chemicals, components, and other materials commonly used in the construction of homemade explosive devices. In addition to the precursor chemicals, the investigation revealed Ellaboudy had also purchased parts used for the construction of drones and remotely operated aerial systems. 

The complaint alleges that in December 2024, the FBI learned that Ellaboudy took sick leave from his employment, claiming that it was due to having been exposed to highly concentrated nitric acid, a common chemical used in the construction of explosive materials. In September 2025, Ellaboudy, using an official passport previously issued to him when employed by the U.S. Army Corps of Engineers, traveled from Richland, Washington to Oman. Upon arriving in Oman, Ellaboudy used this same passport to cross the border into Yemen with the intent on traveling to Sanaa, Yemen, the country’s capital, which is under the control of the Houthis. Upon returning to the United States, Ellaboudy stated to U.S. Customs and Border Protection Officers that he had travelled overseas on official government business. Subsequent information from Ellaboudy’s DOE supervisor revealed he did not have any authorized official government travel to that region. 

Well, that's not a great example of home chemistry.
