Several people were shot on Thursday in Perryman, Maryland, near an Army facility, according to authorities.
It was not immediately clear whether anyone had been killed, and details of the incident remained largely unknown as of 11 a.m. EDT (1500 GMT).
“The situation is still fluid,” the Harford County Sheriff’s Office wrote on Twitter, adding that officers were dispatched to the incident shortly after 9 a.m. EDT (1300 GMT). The sheriff’s office said it would brief reporters around 11:45 a.m. (1545 GMT).
Agents from the Baltimore offices of the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) and the FBI were also responding, the agencies said.
Perryman is 34 miles (55 km) northeast of Baltimore. The area of the reported shooting includes a church and a business district. It is a few miles from the Aberdeen Proving Ground, a large Army facility where military technology is developed and tested, according to Harford County’s website.
A witness told NBC’s affiliate in Baltimore that the shooting appeared to have occurred at a Rite Aid distribution center.
“There’s a lot of police activity and ambulances and fire engines,” David Graf, an employee at a nearby local automotive repair shop that was on lockdown, told WBAL. “There’s not any way to get out of the area, so I can only imagine there’s still someone they’re searching for.”
Governor Larry Hogan said his office was “closely monitoring the horrific shooting.”
“Our prayers are with all those impacted, including our first responders,” Hogan wrote on Twitter. “The State stands ready to offer any support.”
The shooting occurred a day after a man shot and wounded four people, including a police officer, at a Pennsylvania court building before he was killed by police, according to Pennsylvania State Police.
Carl Bernstein: There are 7-9 ‘wobbly’ Republicans who want witnesses but Mitch McConnell is trying to block them
In a CNN panel discussion Wednesday, notorious Watergate reporter Carl Bernstein revealed that there are seven to nine Republican senators who are wavering after the compelling argument that the House has provided for the impeachment. The problem, however, is that Senate Majority Leader Mitch McConnell (R-KY) is refusing to allow any break from the party line.
"I think this is a hugely damaging narrative that was laid out today, and that Mitch McConnell understands, and has understood for a while that this hugely damaging narrative was going to affect his members," said Bernstein. "And that his strategy -- I've talked to some Republicans about this -- #MidnightMitch is to wear out his own members so that they don't vote for more witnesses because there are six, seven, eight, nine wobbly Republicans."
Republican Kevin McCarthy gets taken down by former top GOP colleague
Rep. Kevin McCarthy (R-CA) was attacked by a former Republican colleague who alleged McCarthy and his fellow members of Congress have allowed the House GOP to become the official shill for the White House.
In a profile for the New York Times, former Oversight Committee Chairman Tom Davis (R-VA) shamed the GOP House for the way that a once-respectable institution has fallen.
“Congress no longer operates as an independent branch of government, but as an appendage of the executive branch,” said Davis. “He is made for that role.”
Former senator reveals to Maddow how one brave Democrat can reveal key document in impeachment trial
Near the end of Wednesday's impeachment trial, Chief Justice John Roberts announced that an agreement had been made to allow senators to read supplemental testimony from Vice President Mike Pence aide Jennifer Williams.
The document will remain classified, despite claims that there is no classified material in the document, only evidence that is damning to the president.
"In terms of this document potentially being improperly classified, which is something that has been raised in writing by Rep. Adam Schiff (D-CA) and raised on the floor of the Senate tonight by Rep. Zoe Lofgren (D-CA)," MSNBC anchor Rachel Maddow noted. "Obviously, it was the vice president's office that said it was classified, they are getting publicly criticized for that. If it has been improperly classified and it should be something that the public can see, who adjudicates that?"
