A nine-year-old boy with muscular dystrophy melted hearts across the country when he hugged President Donald Trump at the Right to Try Act signing on Wednesday.

The bill gives patients who have potentially terminal illnesses the right to use experimental medications that have not yet been approved by the U.S. Food and Drug Administration.

"Today I am proud to keep another promise to the American people as I sign the Right to Try legislation into law," Trump said. "We're going to be saving tremendous numbers of lives."

After Trump signed the bill, Jordan McLinn, of Indianapolis, approached the president to express his gratitude. Trump pulled him in for a hug and planted a kiss on his forehead in a heartwarming moment.

Jordan and his mother, Laura McLinn, appeared on "Fox & Friends" on Saturday to share their story and how the Right to Try bill will help families like theirs.

Laura revealed that when Jordan was almost four years old, he was diagnosed with Duchenne muscular dystrophy, a fatal muscle-wasting disease that affects approximately one in 3,500 boys.

More than five years later, Jordan is part of a clinical trial and he's doing great.

His mother said the family continued to campaign for Right to Try because it could give patients like Jordan access to potentially life-saving medications.

She said she wanted to give a big "thank you" to President Trump and Vice President Mike Pence, who has also been a longtime supporter of the measure dating back to his days as governor of Indiana.

"There are just no other words. We're just so honored and grateful that they were so supportive of Right to Try and just helped us get this across the finish line."
