Seven people experienced brief illness after opening a suspicious package on Thursday at Joint Base Andrews, a military facility near the US capital that houses Air Force One, the presidential aircraft. This was confirmed by a base spokesperson on Friday.
The package expressed "negative sentiments" toward President Donald Trump but contained "no specific threats towards the president or other government officials," according to the Joint Base Andrews spokesperson.
"Emergency responders evacuated the building and connecting building and established a cordon around the area," the statement said.
"Seven individuals felt ill and were assessed by the JB Andrews medical team and were released."
Earlier reports from US media suggested the package contained a white powder. Joint Base Andrews, located in Maryland just a short drive from Washington, is frequently used by senior government officials. President Trump had recently arrived there on Wednesday, returning from a business forum in Florida aboard Air Force One.
The suspicious package at Joint Base Andrews caused temporary illness in seven people but no harmful substances or threats were found, ensuring safety at the presidential military base.
