WASHINGTON – Queens Rep. Gregory Meeks’ Capitol Hill office was evacuated today and police called in after a staffer found a “suspicious powder” in the mail – but it was a false alarm, officials said.

After US Capitol Police and a HAZMAT team cordoning off Meeks’ office in the Rayburn House Office Building, test indicated that the powder was not dangerous.

“All test results were negative. The area has reopened,” Capitol Police announced in an email to Congress members and staff.

It was unclear what type of powdery substance caused the false alarm.

Capitol Hill lawmakers and workers have been on edge since letters laced with the poison ricin were intercepted two weeks ago en route to President Obama and Sen. Roger Wicker (R-Miss.).

“Earlier this morning a staffer was going through a stack of mail and a suspicious powder substance was found,” said Meeks spokeswoman Candace Sandy.

She said that Meeks was in New York and not at his Washington office when the suspicious powder was discovered, but he was very concerned.

Capitol Police first alerted Congress members and staff of the incident around 12 p.m. and sounded the all clear about two hours later.
