Former McConnell aide Josh Holmes called the Senate special election a "national embarrassment" as embattled GOP Senate candidate Roy Moore went against Democrat Doug Jones in what had become a competitive race in a deeply red state.

Bannon, the executive of the right-wing Breitbart News, appeared with Moore on the campaign trail twice in the final week leading up to election day Tuesday, taking time at each one to specifically rail against McConnell and other Washington Republicans.

McConnell previously called on Moore to withdraw from the race in the face of mounting allegations against Moore from women saying he pursued them when they were teenagers and he was in his 30s. He also said Moore would likely face a Senate Ethics Committee probe if elected.

McConnell and Bannon have frequently clashed. McConnell has said Bannon and his allies are “specialists at nominating people who lose.”

Bannon has reportedly asked potential GOP primary challengers to commit to voting against McConnell for leadership if elected and has vowed McConnell will not be the Senate majority leader next year.
