In his Talking Points Memo tonight, Bill O'Reilly weighed in on the recent war of words between Donald Trump and Jeb Bush, and what it reveals about the state of the Republican Party.

On "Fox News Sunday," Trump said that Bush's assertion that his brother George W. Bush kept the country safe is not true, because 9/11 occurred on his watch.

Trump explained that he doesn't blame the former president for the terror attacks, but but doesn't believe President Bush kept us completely safe either.

"While the Trump-Jeb Bush back-and-forth may be good copy, it really serves no purpose," O'Reilly said.

"The Factor" host noted that this Trump-Bush story distracted from Mitt Romney's critique of Hillary Clinton over the weekend.

"That might have been just a standard interview by Gov. Romney, but I suspect there may be something else in play," O'Reilly said. "It is entirely possible that no Republican contender will lock things up in the early primaries. If that's the case, the GOP could turn to Mitt Romney."

"The governor received more than 59 million votes last time around, he is well known, has establishment support. Something to consider."
