"We need a president who understands technology in the Oval Office," Fiorina told the GOP undercard debate audience in South Carolina on Thursday night.

"No, Mrs. Clinton, you cannot wipe a server with a towel," Fiorina said. During the height of the political controversy over her use of private email while serving as secretary of State, Clinton emphasized her ignorance of how data could be wiped.

Fiorina, a former CEO of technology company Hewlett Packard, was demoted from the main debate stage after slipping in recent polls, and she spent the first portion of the debate attacking Clinton. 

In her opening remarks, Fiorina suggested Clinton has a loveless marriage and followed by accusing the Democratic front-runner of being in thrall to corporate donors.
