The student, named Sarah Chadwick, who attends Marjory Stoneman Douglas High School, responded to the president’s post on Wednesday evening, in which he wrote: “My prayers and condolences to the families of the victims of the terrible Florida shooting. No child, teacher or anyone else should ever feel unsafe in an American school.”

The poignant message was retweeted thousands of times, as officials revealed details of the shooting which left 17 dead and several others injured.

Many politicians made similar calls for stricter gun control.
Among them was Democratic Sen. Chris Murphy, who said Congress was to blame for the numerous school shootings that have recently taken place in the country.
“This happens nowhere else other than the United States of America, this epidemic of mass slaughter, the scourge of school shooting after school shooting,” he said Wednesday, while speaking in the Senate.

“It only happens here not because of coincidence, not because of bad luck, but as a consequence of our inaction.”
Colorado Sen. Michael Bennet also demanded action, tweeting: “When did mass shootings become a normal part of American life?”
Bennet then offered his thoughts to the victims, acknowledging they “are not enough.”
Several Republican politicians also spoke out after shooting, offering their prayers.
Tweets by some politicians garnered more fury than praise, with many responding that “thoughts and prayers” won’t solve the country’s gun violence problem.
Among those criticizing the politicians was Bess Kalb, a writer for the Jimmy Kimmel Live show. Kalb responded to the politicians’ tweets by revealing how much in campaign donations they received from the National Rifle Association (NRA).
According the L.A. Times, the gun rights advocacy group spent a total of $54.4 million durng the 2016 election campaign — the newspaper explains the money was used “for or against a candidate but not a direct contribution to a campaign.”
Out of that amount, $52.6 million was spent on Republicans, and Democrats received $265.

The NRA spent more than $30 million to help elect Trump as president, including about $19 million on attack ads aimed at his opponent Hillary Clinton.
Trump spoke out about the shooting further on Thursday, blaming the incident on the shooter’s mental health.

Nikolas Cruz, 19, has been charged with 17 counts of premeditated murder.
“So many signs that the Florida shooter was mentally disturbed, even expelled from school for bad and erratic behavior,” he tweeted.
In a televised statement hours later, he reiterated the same sentiment, saying he plans to visit the school soon.
He did not take questions from media on gun control.
