The GOP presidential candidate was a bit touchy Wednesday when questioned by reporters about claims he sexually harassed two women in the late 1990's during his time as head of the National Restaurant Association.
"Don't even bother asking me all of these questions," Cain said to reporters.
Then the conservative businessman raised his voice.
"Excuse me," Cain yelled. "What part of no do you not understand," he asked.
The incident occurred inside a Northern Virginia hotel where Cain met with a group of conservative physicians.
Cain's security staff then pushed their way through a scrum of reporters and photographers to escort the candidate into a conference room where he made a statement to the doctors.
Reporters attempted to ask Cain whether he would call on the National Restaurant Association to release the two women from non-disclosure agreements that they reportedly signed in order to receive settlement payments from the lobbying group.
A lawyer representing one of the women told CNN he plans to ask the National Restaurant Association for a release from those agreements, citing Cain's comments as a potential violation of the conditions of those settlements.
Cain's Chief of Staff, Mark Block indicated talks to release the women from their non-disclosure agreements may be underway.
Holding a phone up to his ear, Block said to CNN: "This may be the call now."
"Should be an interesting 48 hours," he added.
The story on the harassment complaints and settlements were first reported by POLITICO.
Cain has denied he sexually harassed the women.
