South Carolina Democrat Archie Parnell physically abused his former wife in the 1970s, according to court documents unearthed by his campaign and obtained by The (Charleston) Post and Courier.

Parnell’s campaign manager and his finance manager have quit, according to a source close to the campaign.

Ohio Rep. Tim Ryan, who campaigned with Parnell during the special election for South Carolina’s 5th District last year, rescinded his endorsement of Parnell on Monday night.

South Carolina Democratic Party Chairman Trav Robertson has called on Parnell to step aside.

But Parnell is refusing to drop out of the race, which he came close to winning last year against Republican Ralph Norman.
