Good morning, D.C. The top news this morning is still Monday evening’s fatal collision between a D.C. National Guard vehicle and a cyclist. We now know that the vehicle in question was a 5-ton transport truck, and not a Humvee, as had been originally reported. At the time of the incident, the truck’s driver was pulling in to the intersection of 12th Street and New York Ave. to block it off to make way for a motorcade heading to the Nuclear Security Summit at the Washington Convention Center. WTOP says that there may be a video of what happened, which D.C. Police are reviewing. The victim has yet to be identified.

Police Investigated in UMd. Beatings: Last month’s chaotic post-game celebration at the University of Maryland in College Park has now led to a criminal investigation of three Prince George’s County police officers, the Washington Post reports. Disturbing video showing a brutal, seemingly unprovoked beatdown has been released an attorney for one of the students, who also describes charging documents against his client as “nothing more than a cover.” One officer has already been, and two others may also be soon once they are identified.

Are Teacher Raises Covered by the Mayor’s Budget? More from the Post’s Nikita Stewart on Monday’s budget presentation by D.C. Mayor Adrian Fenty, with an emphasis on that tentative agreement between the city and the Washington Teachers’ Union. D.C. Council members pressed the mayor on whether the money for those 20 percent salary raises for teachers is really all there. The administration didn’t do a great job answering that question: CFO Nat Gandhi ‘said he would have to study the contract and the budget. “I think it’s somewhat premature for me to say that that contract doesn’t make sense,” he said.’
