(CNN) - Mitt Romney said Monday he would consider removing a television ad produced entirely from a clip of NBC's evening news program, though the candidate wouldn't say definitively he would take the ad down.
"We'll sit down with the lawyers, talk to the folks at NBC, and make a decision on that front," Romney said on NBC's "Today."

He added, "Obviously this was not something taken from hidden files. This was on the evening news. So it should hardly come as a revealing piece for people who watch it."
The ad in question is produced wholly from a 1997 clip of NBC "Nightly News" in which anchor Tom Brokaw announced the House Ethics Committee's decision to penalize then-Speaker Newt Gingrich. The ad began airing Friday, and received an enormous amount of media attention over the weekend. Romney's campaign said Saturday they believed the clip "falls within fair use," meaning it doesn't violate copyright laws.
In a statement Saturday, Brokaw said he was "extremely uncomfortable" with the ad, adding, "I do not want my role as a journalist compromised for political gain by any campaign." NBC's legal department sent a letter to Romney's campaign requesting all NBC material be removed from their political advertisements.
Romney said the ad was part of a larger move by his campaign to fight more aggressively against Gingrich's attacks, saying the experience of losing South Carolina sparked a new fierceness in his operation.
"We were being whaled on by Speaker Gingrich and didn't respond well in South Carolina," Romney said. "So we decided to respond. We made it clear if people want change in Washington you have to bring in someone from outside Washington. Both the change in tactic as well as the message have had a real impact in Florida."
On Fox News' "Fox and Friends," Romney said his rival's own negative attacks revealed a degree of desperation.
"You know, desperate times, I guess," Romney said. "It really has been very sad and painfully revealing about the speaker to see him railing on like this. It helps us understand why it is that of the hundreds of people that worked with him as speaker, only a handful are willing to support him."
