Kimmel says former Presidents Clinton, Bush and Obama reached out about his son

The late night host's son, Billy, required heart surgery when he was born.

Kimmel, 49, spoke out three months ago about his son, Billy, who required surgery for a heart defect just days after he was born. During an emotional monologue on his ABC show, "Jimmy Kimmel Live!" he pleaded with politicians to come together to ensure health care for all Americans, particularly those who have pre-existing conditions.

"I knew I had to say something, and I knew that I would get emotional. It occurred to me that maybe we could make it into something positive," he told the Hollywood Reporter. "I had a lot of time to think at the hospital, and it just so happened that our government was deciding whether or not millions of people should have health care at that time. I think it made a big impact on American citizens. I'm not sure, based on how our so-called leaders voted, whether it made a big impact on the Senate or House."

As for his son, Kimmel told the publication that he will need two more surgeries, but is "doing great." Late last month, the comedian and his wife, Molly McNearney, shared photos of the 3-month-old boy and encouraged their followers to stay politically active.

"Remind your Congresspeople that every kid deserves the care [Billy] got," Kimmel wrote.
