Former Hewlett-Packard chief executive Carly Fiorina on Monday joined a crowded Republican field as she announced her 2016 White House run, USA Today reported.

The 60-year-old businesswoman kicked off her campaign with a conference call, television interview and online town hall. She used the events to tout her business experience and criticize Hillary Clinton, the Democratic front-runner -- and so far the only other female candidate of either party.

"I think I'm the best person for the job because I understand how the economy actually works," Fiorina said on ABC's Good Morning America. "I understand the world, who's in it, how the world works."

Clinton, meanwhile, was "clearly not trustworthy" because she had not been "transparent" about her State Department emails, the 2012 attack on the U.S. consulate in Benghazi, Libya and foreign contributions to the foundation of her husband, former President Bill Clinton, Fiorina insisted.

On social issues, Fiorina branded herself as a conservative, the Wall Street Journal noted, even though she had granted benefits to gay and lesbian couples as HP chief and opposed a constitutional amendment to prohibit same-sex marriage, a position she maintains.

The Texas native is also against the Common Core national education standards and the Affordable Care Act, better known as Obamacare.

She has further promised to close the Export-Import Bank, which finances and insures foreign purchases of American goods for customers who cannot or will not accept credit risk. Fiorina said the federal agency was emblematic of a problematically close relationship between big business and government.

"We have two structural problems in this economy: One, we are tangling people's lives up in a web of dependence" through welfare programs that discourage entrepreneurial risk-taking, she said. "What we need to do is recognize that while big companies are really important, it's the little guys that are the engine of growth in this economy."

Fiorina has not not held elected office so far. In 2009, she failed in her attempt to unseat California Democrat Barbara Boxer, who ended up winning a fourth term in the U.S. Senate.
