Good morning, Washington. “Hundreds of thousands” of people are expected to descend upon the National Mall for the unveiling of the Martin Luther King Jr. National Memorial on August 28 — which already has some people salivating over the possibility of using the weekend to highlight the District’s unique plight. (We’re just hoping some of them bring plenty of hilarious signs.) Mayor Vince Gray and company will be unveiling their plans to celebrate the memorial’s unveiling later this morning.

Teen Arrested in Lesbian Attack: The investigation into an attack on a group of lesbian women outside the Columbia Heights Metro station has led to an arrest. Last night, D.C. police took 19-year-old D.C. resident Christian Washington into custody and charged him with assault. The women involved in the incident claimed that two men verbally and physically assaulted them on July 30; authorities are continuing to investigate the matter, both in pursuit of the second man and to determine whether police officers ignored the crime when it first occurred. Meanwhile, LGBT activists — claiming that “[i]f it’s a transgendered woman who’s murdered, it’s business as usual, nobody seems to care” — are calling for MPD Chief Cathy Lanier to reinstate a bias policing board.

Mmm, Sausage: Embattled D.C. Councilmember Harry Thomas, Jr. does have one ally: Walmart. Lydia DePillis reports on the sausage-making behind Thomas’ support of Walmart’s forays into the District — in exchange for Thomas’ boosterism, his then-Constituent Services director Ayawna Chase pressed hard for Walmart to donate money to the now-infamous Team Thomas nonprofit which would be used to pay for swag branded with the Walmart logo.

Norton Hosts Job Fair: Yesterday, a record 4,121 people turned out at D.C. Delegate Eleanor Holmes Norton’s annual job fair at the Washington Convention Center, drawing a wide range of individuals looking for salvation from the city’s unemployment rolls. Lines wound up and down the Convention Center, as 100 employers collected applications from a thousand more people than last year’s fair. “This is going to break all records and it is breaking my heart,” said Norton.
