Former HP CEO join US presidential race

The United States presidential election is poised to get even more interesting as a second female candidate has emerged in the person of Carly Fiorina, the former chief executive of Hewlett-Packard (HP).

BBC report Fiorina is likely to be the only prominent female to run for president as a Republican.

The former corporate executive made her big announcement on ABC's Good Morning America programme, saying  she understands "executive decision-making" and shunning the path of other candidates who've held large rallies to announce their candidacy.

While on the show she directly criticised the only other high-profile woman running, Hillary Clinton saying:

"I have a lot of admiration for Hillary Clinton, but she clearly is not trustworthy,"

As evidence, she pointed to what she described as a lack of transparency on issues such as Ms Clinton's use of a private email server, the 2012 attack on an American embassy in Benghazi, and foreign donations to the Clinton Foundation.

Fiorina's primary claim to fame is serving as head of computing giant Hewlett-Packard, a job from which she was ousted after six years amid stockholder unrest.

In 2010, she lost her only run for public office by 10% - the Senate race in California.

Earlier in the day, it also emerged that famed retired neurosurgeon, Ben Carson would be running for president under the Republican ticket.

Both Fiorina and Carson are political outsiders entering a race that is expected to be dominated by senators, and current and former governors.
