A senior official told Fox News that the battle to get Barrett confirmed before Election Day will feature attacks from all sides as Democrats push back on the nomination process.

"We will need to be knife fighters with the opposition, and will be prepared to marshal information quickly, and disseminate it to push back on any false narratives or attacks on her and her family, because we anticipate, unfortunately, that Democrats will go there," the official said.

"So we're mounting an offensive strategy on her behalf because she is such an incredible and inspiring nominee. We'll be defending her fiercely every day."
