Former Hewlett-Packard CEO Carly Fiorina chose ABC News’s Good Morning America this morning as the place to announced she is running for president in 2016 – and plug her book.

“Yes, I am running for president,” Fiorina told George Stephanopoulos. “I think I am the best person for the job.” Fiorina, the first female contender for the Republican nomination, has never held elected office. She lost her 2010 Senate bid in California to incumbent Democratic Sen. Barbara Boxer by 10 percentage points. She was an economic adviser to Sen. John McCain’s 2008 presidential campaign. But, since December, she has traveled the early voting states, blasting Hillary Clinton for her record at the State Department and the Clinton Foundation’s acceptance of donations from foreign governments. During her Hillary bashing tour, she’s been quoted saying, “Like Hillary Clinton, I too have traveled thousands of miles around the globe, but unlike her, I’ve actually accomplished something.”

Fiorina served as the CEO of HP from 1999 to 2005, becoming the first female CEO of a Fortune 50 company.Among the things for which she is known: merging HP with Compaq to make the world’s largest personal computer manufacturer, though HP’s stock lost half its value; she ordered the layoffs of 30,000 HP employees during her time at CEO. She resigned in ’05.

Stephanopoulos asked her, politely, about her complete lack of political experience, having never held a elected government office. Fiorina, 60, explained that’s a plus, because America is “tired of the professional political class.”

Fiorina also sat down with GMA’s Robin Roberts to discuss her new book, Rising to the Challenge: My Leadership Journey.
