Democratic New York Gov. Andrew Cuomo joined a student protest against gun violence in New York City on Wednesday, chanting “gun control now” as he laid on a sidewalk.

In 2013, Cuomo, a supporter of stricter gun laws, passed the New York SAFE Act, which expanded background checks for firearms purchases and restricted access to assault weapons. In the days following the mass shooting at Marjory Stoneman Douglas High School in Parkland, Fla., Cuomo implored the NRA to listen to the students who are demanding tougher gun control.

“As a father and a gun owner, I think it would be nice if the NRA listened to the millions of children across the country who are asking the President and the GOP Congress to stop this senseless gun violence,” Cuomo said.

Students nationwide participated in a “national walkout day” on Wednesday, one month after the Valentine’s Day shooting in Parkland.

National walkout day took many forms, with some students protesting and marching for stricter gun control laws, and others participating in a 17-minute walkout to honor the 17 victims killed in the recent Florida shooting.

Hundreds of students in the Washington, D.C.-area marched to the White House, where they turned their backs on the structure and observed a 17-minute time of silence, The Hill reported.
