President Obama unveiled new policies aimed at reducing gun violence, Wednesday.
He says, society's first job is keeping children safe.
He was joined by four children who had written to the White House in the weeks since the Newtown mass shooting, expressing their fears over the safety of young people in the wake of gun violence.
The President announced proposals that he'll send to Congress, including requiring criminal background checks on all gun sales, banning "military-style" assault weapons, and limiting ammunition magazines to 10 rounds.
The president also signed a series of 23 executive actions strengthening current laws, expanding mental health measures, and promoting federal research into gun crime through the centers for disease control.
He also acknowledged his legislative proposals will meet with opposition from some gun-rights groups, and appealed for public support.
"This is our first task as a society, keeping our children safe.
This is how we will be judged.
And their voices should compel us to change." Said Obama.
Biden formally delivered recommendations to the president on Tuesday.
