President Trump started a speech in Miami, by offering support to Majority Whip Steve Scalise, R-La., and Otto Warmbier, the University of Virginia student who returned to the United States this week after spending more than a year imprisoned in North Korea.

"I'm so glad Secretary of State Rex Tillerson and I, along with a very talented team, were able to get Otto Warmbier back with his parents," Trump said. "What's happened to him is a truly terrible thing, but at least the ones who love him so much can now take care of him and be with him."

Warmbier, 22, was detained at Pyongyang Airport in North Korea in January 2016. North Korean officials sentenced Warmbier to 15 years of hard labor in March 2016 for allegedly committing a "hostile act" against the country after security footage emerged of him attempting to steal a banner hanging in his Pyongyang hotel.

Warmbier was released earlier this week and returned home to his family in Ohio. However, doctors at the University of Cincinnati Medical Center said Thursday the 22-year-old was in a state of "unresponsive wakefulness" and had suffered loss of brain tissue in all regions of his brain.

Trump also praised Majority Whip Steve Scalise, R-La., who remains in critical condition following Wednesday's shooting at the GOP's baseball practice in Alexandria, Virignia.

"Also, my dear friend Steve Scalise took a bullet for all of us, and because of him and the tremendous pain and suffering he's now enduring — and he's having a hard time, far worse than anybody thought — our country will perhaps become closer, more unified, so important," Trump said. "So we all owe Steve a big, big thank you."

Scalise was shot in the hip when a gunman opened fire on the GOP's baseball practice. The shooter, identified as James Hodgkinson, 66, of Belleville, Ill., shot and wounded three others: Capitol Police Special Agent Crystal Griner, congressional staffer Zack Barth and Tyson Foods lobbyist Matt Mika.

Before announcing his changes to U.S. policy toward Cuba, Trump went on to offer thanks to the police officers at the shooting and urged those in attendance to keep the Scalise and Warmbier families in their thoughts and prayers.

"Let's keep the Warmbier family and the Scalise family and all of the victims of the congressional shooting in our thoughts and prayers," Trump said. "It was quite a day, and our police officers were incredible, weren't they? They did a great job."
