Rep. Tom MacArthur (R-NJ) talked to Steve Doocy this morning after facing constituents, many of them furious over the House's passage of an ObamaCare replacement bill. 

One man, a health care industry employee named Geoff Ginter, was particularly intense, pointing at MacArthur and calling him the "single greatest threat" to his family.

The man said his wife beat cancer, but they worry that it could return and that their two children both have pre-existing medical conditions. He expressed concern that under the American Health Care Act, they could lose coverage.

MacArthur leads the Tuesday Group, a collection of moderate House Republicans who hammered out a deal with the conservative Freedom Caucus on a bill that narrowly passed the House last week. 

He said on "Fox & Friends" this morning that he tried to just listen to the man as he talked for about 10 minutes. 

"I wanted to hear his concerns. It was five hours, but I promised everyone would get to speak. I tried to hear them. People are scared. I get that," he said.

MacArthur has emphasized recently that he deeply understands the health care issues, having lost his mother to cancer when he was four years old and his daughter, who died at age 11.

During the five-hour forum Wednesday night, as attendees shouted "shame" and "liar" at him, MacArthur defended the AHCA, arguing it is a badly-needed replacement for ObamaCare. 

He said the current system must be fixed, since the ballooning cost of health care "will swallow us all alive."

"There's a lot of fear and anger. We're gonna have to press through it and help people understand," said MacArthur.
