(CNN) — Former Republican presidential nominee Mitt Romney will attend an interfaith service honoring those who suffered or lost their lives in the Boston bombing, two sources close to Romney confirmed.
President Barack Obama is also scheduled to be at the event, the White House announced Tuesday.
Romney, a former Massachusetts governor who ran his presidential campaign from Boston, was invited to the service by the state's current chief executive, Deval Patrick.
Romney now serves as a chairman of a committee for the Boston-based Solamere Capital, the investment firm founded by his eldest son, Tagg.
Romney made a rare comment via Twitter shortly after the bombings near the finish line of the Boston Marathon. Three people were killed and 180 wounded.
For his part, Tagg said the person or persons responsible for the bombing, being investigated as a terrorist act, "messed with the wrong people."
"It's such a cowardly act, whoever did this," Tagg Romney said Tuesday on CNN's "Starting Point."
"Then you see the warmth of the first responders, and the people around who rushed to the scene. Such a contrast to their bravery. It just really is a family event. And it's the best of Boston. It's wonderful to see how people have been responding and how people are pulling together."
Romney and Obama were at the same venue in late November following the election when the president invited his former opponent to the White House for lunch.
