President Obama welcomed the Boston Red Sox to the White House today. He spoke about the Boston Marathon bombing as the one year anniversary approaches.

Boston Victim & Hero Rescuer Throw First Pitch at Red Sox Game

The president remembered the two firefighters killed in last week’s Boston blaze, Lt. Edward Walsh, 43, and Firefighter Michael Kennedy, 33.

“Their sacrifice, like the sacrifice of those who made last year, remind us of the selfless courage of everyday heroes who put their lives on the line to help others,” he said. “The first responders, the brave citizens, the resolute victims of these tragedies, they’re all Boston strong.”

Despite being a Chicago White Sox fan, President Obama commended the Red Sox for their 2013 World Series win and for bringing the Boston together after the attacks. “It was a drive to do more for the city that had their backs.”

The 118th Boston Marathon will take place on Monday, April 21.
