President Trump wrote a letter to the family of one of the victims of the Marjory Stoneman Douglas High School shooting, thanking them for coming to the White House a week after the shooting to attend a listening session.

The letter was posted on Twitter by Meadow Pollack’s brother, Hunter. Meadow was among the 17 killed in the February 14 shooting at the school.

“Our entire Nation mourns the tragic loss of Meadow. Our hearts are heavy for you and your entire family,” the March 12 letter says.

“I am deeply grateful for your presence at the White House for discussions regarding school safety. I was touched by the memories of Meadow you shared. It was clear that she had a bright future, full of tremendous potential—I know that you were so proud of her,” Trump wrote.

“We will not forget her life, and we are resolved to confront the evil that so senselessly took her from us,” he added.

Meadow’s father, Andrew, a Trump supporter, asked the president last month to put an end to school shootings once and for all.

"We as a country failed our children. This shouldn't happen," he said at the White House listening session.

"It stops here with this administration and me," he said. "It should have been one school shooting and we should have fixed it. I'm pissed. Because my daughter, I'm not going to see again. She’s not here. ... It’s enough. Let’s get together, work with the president and fix the schools."

He said if measures could be implemented after terror attacks, something can be done about school shootings.

"I'm very angry that this happened because it keeps happening. 9/11 happened once and they fixed everything. How many schools, how many children have to get shot?" he said. "I can't get on a plane with a bottle of water but some animal can come into a school and shoot our children."

He continued: "We have to come together as a country, not different parties, and figure out how we protect the schools. It's simple. It's not difficult. We protect airports, we protect concerts, stadiums, embassies, the Department of Education that I walked in today that has a security guard in the elevator. How do you think that makes me feel?"
