Seven people were briefly hospitalized after opening a suspicious package containing a white powder at Joint Base Andrews, a military base near the US capital that houses Air Force One, the presidential jet, US media reported.
The CNN network reported that initial tests by a HAZMAT team found the substance was not hazardous, though the investigation continues. Those hospitalized on Thursday were later released, according to CNN.
Fox News noted that some individuals experienced headaches. CNN cited sources familiar with the case, stating the package also contained what was described as "political propaganda."

Located in Maryland, Joint Base Andrews is a short drive from Washington, D.C., and is frequently used by senior US government officials.
