(RNN) - Carly Fiorina has suspended her campaign for the Republican nomination for president, she announced Wednesday on Twitter.
The former Hewlett-Packard leader tried to use her business background and secretary-to-CEO story to carve out a following in the GOP race. Fiorina, 61, also positioned herself as a female Republican alternative to Hillary Clinton.
In her statement, she said she would continue to travel the country and "fight for those Americans who refuse to settle for the way things are."
"This campaign was always about citizenship - taking back our country from a political class that only serves the big, the powerful, the wealthy and the well-connected," she said. "Election after election, the same empty promises are made and the same poll-tested stump speeches are given, but nothing changes. I've said throughout this campaign that I will not sit down and be quiet. I'm not going to start now."
Despite what many said were appealing appearances in debates, she failed to gain significant support and finished seventh in Iowa, garnering 1.9 percent of the vote.
Fiorina used opposition to Planned Parenthood as a cornerstone of her campaign, using the secretly recorded videos alleging illegal activity by the organization as a jumping-off point.
She started off polling low and was relegated to the "undercard" of the GOP debates, but climbed in the polls and reached the main stage. However, following the Iowa Caucuses, she did not qualify for a debate leading up to the New Hampshire primary.
Fiorina was considered one of the top female business executives when she was head of Hewlett-Packard, a position she held from July 1999 until February 2005. She oversaw the company's controversial $19 billion merger with Compaq in 2001, in which more than 17,000 employees lost their jobs.
She has targeted Clinton's record as secretary of state, claiming that "she didn't accomplish anything as secretary of state."
Fiorina's previous forays into the political arena have been on behalf of losing causes. She was an adviser to Sen. John McCain's 2008 presidential bid, and in 2010, she unsuccessfully challenged Sen. Barbara Boxer, D-CA, for the U.S. Senate.
In 2009, Fiorina battled breast cancer and had related surgery.
Fiorina is married with one living step-daughter and one deceased step-daughter, both of whom Fiorina helped raise.
