Obama phones Gov. Patrick, Mayor Menino

A correction from the original statement from the WH, which had said two officers were killed overnight.

On background from a White House official:

“The President continues to be briefed on the investigation by his national security team. The most recent briefing, provided in the Oval Office by Assistant to the President for Homeland Security and Counterterrorism Lisa Monaco, concluded shortly after 4 p.m. Following that briefing the President placed calls to Governor Deval Patrick and Boston Mayor Thomas Menino, to express his condolences for the MIT police officer who was killed overnight. The President said that the entire country is behind the people of Boston as well as Massachusetts, and that the full force of the Federal Government will continue to be made available until those responsible are brought to justice.”
