Former technology executive Carly Fiorina says she is more than 90 percent likely to seek the Republican presidential nomination. And she is questioning the confidence people can have in likely Democratic contender Hillary Rodham Clinton.

On "Fox News Sunday," Fiorina challenged several Clinton comments, including saying she used a personal email account for State Department work because it would be easier to carry one device than two. She said such statements raise a confidence issue about the former secretary of state, senator and first lady.

Fiorina also said Clinton is not candid. She said that "suggests her character is flawed."

Fiorina, who has attacked Clinton before, is former CEO of the Hewlett-Packard Co. She lost a 2010 California race for the U.S. Senate.
