WASHINGTON (AP) Neil Heslin says it's all about his slain son, Jesse.
The 50-year-old construction worker is in Washington to testify to the Senate Judiciary Committee today in support of legislation by Democratic Senator Dianne Feinstein of California to ban assault weapons.
Heslin says he's gotten involved because of his boy, who was one of 20 first-graders and six staffers who were fatally shot at Sandy Hook Elementary School in Newtown, Conn.
Other witnesses include William Begg, an emergency room doctor who treated Newtown victims that day.
Across the Capitol, the House Education and Workforce Committee plans to hear from school safety experts and counselors about how to keep students safe. Witnesses before the Republican-controlled House panel are expected to emphasize the role of school resource officers, who are sometimes armed.
