President Trump awarded a Purple Heart Saturday to an Army sergeant who was wounded in Afghanistan.

In his first visit to Walter Reed National Military Medical Center, the president and First Lady Melania Trump gave the military honor to Sgt. First Class Alvaro Barrientos, whose right leg was amputated below the knee after he was wounded on March 17.

“When I heard about this, I wanted to do it myself,” Trump said at a ceremony in the hospital atrium. “Congratulations. Tremendous.”

The president kissed Barrientos’ wife, Tammy and shook Barrientos’ hand before pinning the medal on the wheelchair-bound sergeant’s shirt. After the ceremony, the president met privately with a dozen service members for about 90 minutes.
