Four years ago today, three people were killed and dozens more were injured when Islamic terrorists detonated two bombs near the finish line of the Boston Marathon.
Since 2015, April 15 has been known as "One Boston Day" in the city to honor those killed or injured and to "celebrate the resiliency, generosity, and strength demonstrated by the people of Boston and those around the world" in response to the attack.
Here's how political figures chose to remember that day, and the strength of the city in the face of unspeakable evil:
Boston represents what it means to never yield, never cower, never stand down & lead the way. America owns the finish line. #OneBostonDay

Saturday is the 4-yr anniv of the Marathon bombings. We remember the victims of that tragedy, but also the generosity of many in its wake.
