Limbaugh said that any immigration reform including a pathway to citizenship would amount to amnesty, but that there wouldn't be much Republican opposition to it.

"It's up to me and Fox News, and I don't think Fox News is that invested in this. I don't think there's any Republican opposition to this of any majority consequence or size. We'll have to wait and see and find out. But this is one of those, just keep plugging away, plugging away, plugging away until you finally beat down the opposition," Limbaugh said.

Limbaugh's comments were a reference to a suggestion by President Barack Obama that Limbaugh and Fox News were part of the reason compromise is a "dirty" word in Washington.
