The Washington DC office of a local congressman has been allowed to reopen following an earlier scare involving suspicious mail.
NY1 is told a staffer opening Queens Congressman Gregory Meeks' mail discovered a suspicious substance.
Authorities say Meeks' office was temporarily cordoned off and the staffer was briefly quarantined.
It's still not clear what the substance was.
Meeks was not inside the office at the time.
Today's incident comes two weeks after mail containing ricin was sent to President Barack Obama and Mississippi Senator Roger Wicker.
A Mississippi man has been arrested in connection with those incidents.
