Barack Obama and Hillary Clinton were moved by Jimmy Kimmel's emotional plea for Obamacare in which he tearfully revealed his newborn son has a heart defect.

"Watch and prepare to tear up," Clinton tweeted, thanking Kimmel for "reminding us what's at stake" in the healthcare debate.

"Well said, Jimmy," Obama responded. "That's exactly why we fought so hard for the ACA, and why we need to protect it for kids like Billy. And congratulations!"

During Monday's "Jimmy Kimmel Live," the host described what it was like to find out his newborn had a rare heart defect that required surgery.

"It's a terrifying thing," Kimmel said through tears. "It was the longest three hours of my life."

Kimmel went on to defend Obamacare.

"You know, before 2014, if you were born with congenital heart disease, like my son was, there's a good chance you'd never be able to get health insurance, because you had a pre-existing condition," Kimmel said, defending Obamacare.

The comedian thanked Congress for bolstering National Institutes of Health funding by $2 billion after President Trump proposed more than a billion in budget cuts to the agency.

He broke into tears again as he begged Americans to "stop with the nonsense" over healthcare.

"This isn't football. There are no teams," Kimmel said. "We are the team. It's the United States. Don't let their partisan squabbles divide us on something every decent person wants.

"No parent should ever have to decide if they can afford to save their child's life. It just shouldn't happen. Not here."
