Fox Business Senior Correspondent Charlie Gasparino reacted to former Gov. Mitt Romney (R-Mass.) calling out Alabama Senate candidate Judge Roy Moore (R).

Romney tweeted Monday that Moore would be a "stain on the GOP and on the nation."

The 2012 Republican presidential nominee gave credence to the report that Moore hit on and committed sexual misconduct against Leigh Corfman, who was a minor at the time.

"No vote, no majority is worth losing our honor [and] integrity," Romney said.

Gasparino said Romney doesn't have much "to lose" in this situation, since he has been replaced by President Trump as the GOP standard-bearer.

Gasparino said the tweet is another example of the "battle royale" within the GOP, between the populist, nationalist "Bannonites" and the moderate GOP establishment.

He said Romney has proven to be a "man of integrity" in his business and personal life, remarking that the worst thing you could say about the wealthy former businessman is that he "lost to Obama."

Gasparino said the Doug Jones-Roy Moore contest was an "odd choice" for Romney to insert himself in.

He said that, by criticizing Moore, Romney was appearing to accept the candidacy of the liberal Jones.

He said Jones is "very, very left wing" and supports partial-birth abortions in the otherwise socially conservative Yellowhammer State.

Moore later responded, saying Romney either "lost his courage" or doesn't care for the truth.
