'It's still happening': Parkland survivor sobs in the White House during Trump's mass shooting listening session

During President Donald Trump's White House listening session with families and survivors impacted by mass shootings on Wednesday, a Parkland, Florida high school student who lived through last week's massacre sobbed when recounting the terror he experienced.

18-year-old Sam Zeif, a senior at Marjory Stoneman Douglas High School, went viral last week after he posted a text message exchange he had with his freshman brother in the midst of the shooting at their school. Today, he gave an emotional appeal to the president, Vice President Mike Pence and Education Secretary Betsy DeVos about the ordeal.

"I was on the second floor, texting my mom, texting my dad, texting three of my brothers that I was never gonna see them again," Zeif said. "Then, it occurred to me that my fourteen-year-old brother was directly above me in that classroom where Scott Beigel was murdered."

The student went on to rail against the ease with which a shooter can purchase an assault rifle like the one used at Stoneman Douglas last week and in a majority of mass shootings in recent years.

"How is it that easy to buy this type of weapon?" Zeis, who turned 18 the day after last week's shooting, implored. "How do we not stop this after Columbine, after Sandy Hook?"

"I'm sitting with a mother that lost her son," he continued, voice cracking with emotion. "It's still happening."
