The Republican Party's Senate campaign apparatus has severed ties with Roy Moore, a day after the Alabama Senate candidate was accused of engaging in sexual contact with a 14-year-old girl when he was in his early 30s.

According to Federal Election Commission records, the National Republican Senatorial Committee removed itself Friday from a joint fundraising agreement with Moore's campaign. The Alabama Republican Party and the Republican National Committee still belong to the agreement.

NRSC Chair and Colorado Sen. Cory Gardner called the allegations against Moore "deeply troubling" after the Washington Post broke the story on Thursday.

"If these allegations are found to be true, Roy Moore must drop out of the Alabama special Senate election," Gardner, who endorsed Moore in late September, said in a statement.

Four women claimed on the record that Moore pursued them romantically when they were between the ages of 14 to 18 and he was in his 30s. One of the women said Moore initiated sexual contact after bringing her to his home when she was 14.

The former Alabama Supreme Court justice has denied the women's accounts and cast the Washington Post report as "a desperate political attack." The paper endorsed Moore's opponent, Democrat Doug Jones, last month.

Moore raised $2.5 million for his campaign between April 1 and Sept. 3.
