Thursday, First Lady Melania Trump received a visitor at the White House, Kyle Kashuv, a survivor of the mass shooting at a Florida high school last month.

Kashuv, a Republican student who is standing firm for his support of the Second Amendment, has been ridiculed by more liberal students who are fighting for gun control, and have labeled him as an “enemy of the movement,” according to an interview he gave earlier.

Kashuv was also a guest on Fox & Friends Friday morning. (Video below).

The Hill reported:

Kyle Kashuv survived the shooting at Stoneman Douglas last month, where 17 people were killed and several others were injured. The shooting sparked a renewed conversation on gun laws and how to prevent school shootings, largely led by students. 

Kashuv and the First Lady also discussed the ReachOut App, which Kashuv has been promoting in the aftermath of the shooting. The app allows a student to connect with fellow students to discuss emotional or mental problems they’re experiencing.

The first lady sent out a Twitter post Thursday evening, with video clips from her meeting with Kashuv, tweeting:

Heartened to see children affected by tragedy using their voices to try and create change. Wonderful to meet and speak with Stoneman Douglas High School student @KyleKashuv today at the @WhiteHouse. His message of unity inspires us all! #MSDStrong
