Bill O'Reilly dismissed Republican attempts to defund Obamacare on his Thursday show, calling it an example of "fanaticism."
The GOP has been riven by internal conflicts between members who want to vote to defund the health care program once again, and members who have said the effort is doomed.
O'Reilly apparently agreed with the latter, as he made clear on his show.
"Fanaticism on the right is also harming the country," he said, adding, "There is no way Obamacare is going to be defunded. It is not going to happen."
O'Reilly then spoke to Tea Party Express chair Amy Kremer, who wants to defund the program.
"What you are trying to do...is impossible," he said. "Do you not know that?" He added, "I just think it's destructive to your cause."
