Republican Senate candidate Roy Moore defiantly denied allegations of decades-old sexual misconduct with minors published Thursday.

Yet in the span of a tumultuous afternoon, a low-profile special election became a Republican nightmare that threatens a once-safe Senate seat — and offers a new window into ugly divisions that continue to plague the GOP in the age of President Donald Trump.

Republican Senate candidate Roy Moore, a 70-year-old former state Supreme Court justice, defiantly denied allegations of decades-old sexual misconduct with minors published Thursday in a Washington Post story. The revelations, a month before the Dec. 12 special election, triggered a sharp backlash from would-be Republican colleagues on Capitol Hill, who called on Moore to quit the race if the allegations were true.
