The mother of a Newtown, Connecticut, shooting victim is making a deeply personal plea from the White House for all Americans to take action on gun violence.

Francine Wheeler’s 6-year-old son, Ben, was killed inside Sandy Hook Elementary School. She’s stepping in for President Barack Obama to deliver the president’s weekly radio and Internet address. She is the first person to deliver the address other than Obama or Vice President Joe Biden since the two took office in 2009.

Wheeler says thousands of families are drowning in her family’s grief and asks for help to do something, in her words, “before our tragedy becomes your tragedy.”
