Officials released the 911 call made Tuesday stemming from the accusation a SC representative assaulted his wife.
Chris Corley's wife says she and her husband got in a verbal argument Monday night when she said he was "caught cheating".
In the background, Corley's wife is heard screaming, "Don't get in front of the window".
The Aiken Republican faces a felony charge of first-degree criminal domestic violence, which carries a maximum sentence of 10 years in prison, if convicted.
The caller said Corley beat his wife and threatened to kill himself.
Mr Corley, who recently voted for legislation toughening punishments for domestic violence, has been charged with first degree domestic violence and pointing a firearm at a person.
The 911 operator then calls Aiken County 911 and tells the operator that they received a call in which it sounded like children screaming for help and begging their father to stop.
Corley's lawyer told the judge that Corley had never been arrested before, and Abdullah said the sheriff's office had no prior calls to the Corley residence.
Corley's wife said he stopped hitting her only after noticing she was bleeding and hearing the children screaming, deputies said.
According to him, his wife accused him of cheating on her, and lunged at him. The jury meets next week.
The 36-year-old lawmaker, in the presence of an eight-year-old child, caused "physical harm and injury" to his wife, by "striking her about the head and face with a closed fist" and threatening to kill her, "pointing a handgun at the victim causing her to fear for her life".
Corley, who has a pro-gun voting record, is also barred from having a firearm while out on bond. He was elected in 2014 and has a law office in Augusta, Georgia. He co-sponsored a bill that granted reciprocity for gun owners in Georgia, allowing them to carry their weapons in SC and vice-versa.
Corley was little-known as a legislator until he thrust himself into the national spotlight in 2015.
During the debate past year on whether to remove the Confederate flag from Statehouse grounds, Corley suggested replacing it with the white flag of surrender and held up a piece of paper taped to a pencil to illustrate his point.
Corley's holiday card started with: "May your Christmas be filled with memories of a happier time when South Carolina's leaders possessed morals, convictions and the principles to stand for what is right".
