(POLITICO) — The Republican National Committee is withdrawing its support for besieged Alabama Senate candidate Roy Moore, leaving him increasingly isolated as he confronts charges of sexual misconduct with teenagers.

The RNC is pulling out of a joint fundraising agreement it had with Moore, according to a senior party official briefed on the decision. It is also canceling a field program it had set up ahead of the state’s Dec. 12 special election. The committee had about a dozen paid canvassers in Alabama working for Moore. It will no longer transfer any money to the race.

RNC Chairwoman Ronna Romney McDaniel is expected to brief committee members on the decision on a Tuesday conference call.
