Seven people briefly became ill after opening a suspicious package on Thursday at a military base near Washington, D.C., the site that houses Air Force One, the presidential aircraft, a base spokesperson confirmed on Friday.
The package contained "negative sentiments" directed at President Donald Trump, but there were "no specific threats towards the president or other government officials," according to a statement from Joint Base Andrews officials.
"Emergency responders evacuated the building and the connecting facility, establishing a secure 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 by US media indicated the package contained a white powder, but this was not confirmed by authorities.
Located in Maryland, Joint Base Andrews is a short drive from Washington and frequently serves senior US government officials. President Trump arrived at the base as recently as Wednesday following a business event in Florida.
The swift response and medical evaluation resulted in all affected individuals recovering quickly, with no ongoing danger detected at the military base.
This incident highlights the importance of vigilant security and rapid emergency response at critical government sites to ensure safety without causing undue alarm.
