Following a bomb scare, Anthony Brown files papers to run for governor of Maryland Lt. Gov. Anthony G. Brown (D) made his 2014 gubernatorial bid official Friday by filing the necessary paperwork at the Maryland State Board of Elections - but not until a nearby bomb scare delayed him for more than an hour. Prior to Brown's planned 2:30 p.m. arrival, Annapolis police closed down a section of West Street that included the entrance to the election board's offices after a report of a suspicious package across the street outside the Lowes Annapolis Hotel. After a bomb squad detonated the package and police gave the "all clear," Brown and his running mate, Howard County Executive Ken Ulman (D), arrived safely at their destination and filled out the forms that awaited. What took you so long? Elections Administrator Linda H. Lamone joked as Brown entered the building. Brown announced his candidacy back in May, but in Maryland, gubernatorial candidates typically don't file until some time after their announcement. That's in part because candidates are required to have a running mate on board when they file. With Friday's visit, Brown was not the first candidate to file for the governor's race, but he was the first to do so correctly. Brian Vaeth, a retired Baltimore firefighter seeking the Republican nomination, filed in May but his candidacy has been on hold due to a technicality: The person he listed as his campaign treasurer was not registered to vote in Maryland, as is required. Brown faces at least two Democrats in the June primary: Attorney General Douglas F. Gansler (D) and Del. Gansler plans to announce his candidacy Sept. Mizeur launched her bid in July. Neither has made the trip to the Board of Elections yet.
