Republican mega-donor Sheldon Adelson said Tuesday he has no plans to support Steve Bannon in his bid to unseat several GOP incumbents in 2018, days after Roy Moore, Bannon's choice for Alabama's open Senate seat, was accused of sexual misconduct by multiple women.

"The Adelsons will not be supporting Steve Bannon's efforts," Andy Abboud, a spokesperson for the casino magnate, told Politico in a statement.

"They are supporting Mitch McConnell 100 percent. For anyone to infer anything otherwise is wrong," Abboud added.

Bannon met separately with a variety of wealthy GOP donors last month to secure funding for the effort to pit populist candidates against vulnerable Republicans in the midterm elections. Among them was Adelson, a Republican who has spent years cutting seven-figure checks for political campaigns and super PACs.

Adelson's decision to publicly distance himself from the former White House chief strategist came hours after a fifth woman accused Moore of sexually assaulting her when she was in her early teens and he was in his 30s.

McConnell, whose outside group Adelson has contributed to for years, called on Moore to "step aside" early Monday before the fifth woman came forward. Several other GOP leaders echoed the Kentucky Republican by Monday afternoon, leaving President Trump as the only major party figure who has yet to weigh in following the fifth allegation.

Bannon and his allies have stood by Moore in the wake of the scandal, claiming it is up to the people of Alabama to decide if he belongs in the U.S. Senate.
