Bannon's apparent support of Moore puts him on opposing sides with Trump, who endorsed Strange ahead of the Republican primary earlier this month. Trump tweeted numerous times up until the election urging his Alabama followers to vote for Strange.

In the private meeting where he announced his support of Moore, Bannon characterized the race as being between Republican camps who support and oppose the president.

Politico pointed out that Bannon has close ties to Robert Mercer, a megadonor that bankrolled Breitbart and who could steer his wealth to Strange's campaign or outside groups that support the judge.

Moore, who was removed twice from the Alabama Supreme Court, is known for his social conservative positions and recently gained the endorsement of former Alaska Gov. Sarah Palin. During the primary, he gained the support of action hero Chuck Norris and "Duck Dynasty" patriarch Phil Robertson.
