You know that when Fox News host Bill O'Reilly and President Obama sat down for their Super Bowl day chat, that it wasn't going to be a love fest.

In fact it was tense from the very “OK, Bill, you’ve got a long list of my mistakes,” Obama said to The O’Reilly Factor host near the start of their 10-minute live interview on Fox.

Deadline says, that remark — in response to a question from O’Reilly whether it was the biggest mistake of Obama’s presidency when he told Americans no one would lose their healthcare under Obamacare — was one of a number of points on which the two butted heads.

The duo sparred almost from the beginning in the interview live from the White House this afternoon. Obama also took on Fox News Channel when O’Reilly asked him about reports the IRS was investigating Tea Party-related groups for political reasons. “These kind of things keep resurfacing in part because you and your TV station will promote them,” Obama said. “When you look there have been multiple hearings.” Obama denied any corruption, just some “boneheaded decisions.”

Earlier, the Fox News host interrupted Obama with a “you’re not going to answer that?” as the President replied to a question about why he didn’t fire Secretary of Health and Human Services Kathleen Sebelius after the botched online launch of Obamacare.

In the end, the battle between O'Reilly and Obama was more intense than the Seahawks clobbering of the Broncos.
