The tweet came just minutes before LaPierre addressed the 2018 Conservative Political Action Conference (CPAC), during which he lashed out at campaigners and "elites" saying they "hate individual freedom".
"As usual, the opportunists wasted not one second to exploit tragedy for political gain", LaPierre said, adding that 20th-century community organizer "Saul Alinsky would have been proud of the breakneck speed for gun control laws and the breathless national media eager to smear the NRA". He criticized independent Vermont Sen. "And you should be anxious, and you should be frightened. They should have to go through a psychological evaluation and have a doctor or a clinician have to sign their John Hancock and say that person should be given back their Second Amendment right", Israel said.
In his speech, LaPierre warned conservatives that Democrats wanted to "get rid of the Second Amendment" and that they "should be frightened" of a Democrat-controlled Congress or White House. The president is scheduled to host a listening session with students, teachers and parents involved in the Florida shooting as well as the 2012 massacre at Sandy Hook Elementary School in CT and the 1999 mass shooting at Columbine High School in Colorado. They say tougher gun laws do not decrease gun violence.
Once again LaPierre repeated his calls for schools to increase security, even arming schoolteachers, a controversial proposal that even some Republicans have rejected.
"I think the Democrats are the party of Lisa Simpson, and Republicans are happily the party of Homer and Bart and Maggie and Marge", the Texas senator said.
"We share a goal of safe schools, safe neighborhoods and a safe country", LaPierre said, and warned that "evil walks among us". Trump has frequently responded to mass shootings by suggesting that more law-abiding citizens should be armed, echoing LaPierre's comment following the massacre of 20 children and six adults at an elementary school in Newtown, Connecticut, in 2012: "The only thing that stops a bad guy with a gun is a good guy with a gun".
The CNN town hall, "Stand Up: The Students of Stoneman Douglas Demand Action", will also bring together the victims' classmates, parents and other community members, as well as Florida Rep. Ted Deutch and Sens.
Key moments from the discussion centered around gun control, mental health, and a perceived reluctance from lawmakers to make substantial change to the nation's gun laws.
The National Rifle Association spokeswoman, Dana Loesch, took some heat at a town-hall event on gun violence Wednesday night, which featured impassioned dialogue between students, parents, educators, and politicians.
The NRA, for example, is dead-set against raising the age limit.
The sheriff of the Florida county where a rifle-toting teen gunman killed 17 people told a crowd of young people Wednesday that "America is watching you" and that students should continue to push hard for gun control reform. By Thursday morning, Trump tweeted he was committed to pushing for comprehensive background checks and limiting the age of those buying assault-style weapons.
Loesch replied the NRA is waiting on the Justice Department to make a ruling on bump stocks. "Congress is in a mood to finally do something on this issue - I hope!"
