In her address, Fiorina called on Clinton to "please explain why we should accept that the millions and millions of dollars that have flowed into the Clinton Foundation from foreign governments doesn’t represent a conflict of interest."
The Washington Post reported last week that the Clinton Foundation began taking foreign donations after Clinton finished her time as Secretary of State, but it reported Wednesday that the group also accepted millions of dollars from seven foreign governments during her tenure as head of the State Department.
"She tweets about women’s rights in this country and takes money from governments that deny women the most basic human rights," Fiorina said. "She tweets about equal pay for women but won’t answer basic questions about her own offices’ pay standards -- and neither will our president. Hillary likes hashtags. But she doesn’t know what leadership means."
This is not the first time Fiorina, who has said she is considering a 2016 presidential bid, has directly gone after Clinton. At the Iowa Freedom Summit last month she compared her record to Clinton's, something she repeated again in her speech today.
"Like Hillary Clinton, I too have traveled thousands of miles around the globe, but unlike her, I've actually accomplished something," she said last month, but made a similar remark at CPAC today in National Harbor, Maryland. "You see Mrs. Clinton, flying is not an accomplishment. It is an activity."
All of the possible GOP candidates jab Clinton in their speeches, interviews, and even on social media on a regular basis, but Fiorina is the only one of that group of likely candidates who, like Clinton, is also a woman.
At the end of Fiorina’s speech, she did a question and answer session and got in one more jab at Clinton when asked about the importance of female candidates, saying, “I will say this, if Hillary Clinton had to face me on a debate stage, at the very least she would have a hitch in her swing.”
