Before unveiling a series of proposals aimed at strengthening gun control in the wake of last month's Sandy Hook Elementary shooting, President Obama today invited four young children on stage to help him make his case.

After the shooting "I started getting a lot of letters from kids," the president said during this morning's news conference. "These are some pretty smart letters from some pretty smart young people."

Obama proceeded to read aloud snippets from handwritten letters penned by the kids who appeared alongside him: 8-year-old Grant Fritz of Maryland; 10-year-old Taejah Goode of Georgia; 11-year-old Julia Stokes of Washington D.C.; and 8-year-old Hinna Zeejah.

In her letter, Hinna, a third-grader, says one question popped in her head as she watched coverage of the Sandy Hook shooting: "Can we stop using guns?"

Julia's letter, in which she begs Obama to "try very hard to make guns not allowed," elicited a response from the President, who promised Julia he would.

As if offering his understanding in advance, Grant added a P.S. in his letter assuring Obama that "I know you're doing your best."
