A hazardous materials unit and federal agents are investigating a suspicious substance found at the Baltimore office of Rep. Elijah Cummings, officials said. 

City fire spokesman Ian Brennan said the substance was being tested, but referred additional questions to the FBI in Baltimore, whose spokesman declined comment.

Cummings' office is located at 1010 Park Ave., near the Joseph Meyehoff Symphony Hall in Mid-Town. 

Cummings issued the following statement this afternoon:

"When my staff arrived at my Baltimore City District office this morning, they found a putty-like substance on the outside of the front door. The Baltimore City Police were contacted and they sent a bomb technician to analyze the substance. The police advised my staff not to enter the building. The bomb technician determined that the substance was not explosive material and that there was no active threat. The police contacted the Federal Bureau of Investigation (FBI), and officers from the FBI are currently removing the substance and collecting evidence from the front door and surrounding area. Once the FBI completes their work, my staff will be able to enter the building.”
