South Carolina law enforcement and criminal justice officials have given mixed signals about whether or not Rep. Ralph Norman broke any laws Friday when he placed a loaded gun on a table at a meeting with constituents at a local diner.

The South Carolina Democratic Party called for the State Law Enforcement Division and the state attorney general’s office to investigate the incident and for 16th Circuit Solicitor Kevin Brackett to file felony charges against the first-term Republican.

Norman dismissed the Democrats’ request as political nonsense but said he would “welcome any challenges” from his opponents on the issue.

“Let them investigate all they want,” he told the The Herald in Rock Hill, South Carolina, where the incident took place.

Norman said he has “no regrets.”
