As far as I know, Rubio has not responded. Students are walking out and making demands to do something. I know that in the past we've seen a push for control after mass shootings at schools before, but I get the feeling that this isn't going to go away anytime soon. I know that Governor Scott has been very steadfast on being pro-gun, but not so sure how Rubio will hold up with this kind of pressure.
3 billboards near Miami are trolling Sen. Marco Rubio after the Florida school massacre (CNN)"Slaughtered in school"
"And still no gun control?"
"How come, Marco Rubio?"
That's the message scrawled across three mobile billboards seen Friday near Sen. Marco Rubio's office in Doral, Florida. ............
............Rubio, a Republican who ran for president in 2016, said Thursday that gun restrictions would not have prevented the mass shooting at Marjory Stoneman Douglas High School. The senator had received $3.3 million from the National Rifle Association as of October, according to The New York Times.
A person who answered the phone Friday at Rubio's Miami-area office declined to comment on the billboards.
Added Ruby-Sachs: "Today citizens are asking: How come Rubio refuses to protect our children? The senator has taken fire across the country for his toothless response to the shooting, calling it 'inexplicable'. We called (that) 'inexcusable.'"............
