Barack Obama to act on gun violence

Obama, in his weekly recorded address, said he has received “too many letters from parents, and teachers, and kids, to sit around and do nothing”.
He has repeatedly urged Congress to tighten gun laws, with his calls growing louder following the 2012 massacre at an elementary school in Newtown, Connecticut, and again this autumn after mass shootings in Colorado Springs, Colorado, and San Bernardino, California.
