After a week of questions about Hillary Clinton’s ties to the Clinton Foundation during her tenure at the State Department, the Democratic nominee said Friday morning that she is “sure” no damaging emails would be released before Election Day.

During a call-in interview on MSNBC’s “Morning Joe,” co-host Mika Brzezinski asked the former secretary of state, “Are you certain that there are no emails or foundation ties to foreign entities that will be revealed that could perhaps permanently impact your presidential prospects?”

“Mika, I am sure,” Clinton replied. “I’m sure because I have a very strong understanding that the kind of work that the foundation has done, which attracted donors from around the world, is work that went right into providing services to people.”

She went on to say that neither she nor her husband, former President Bill Clinton, nor their daughter, Chelsea Clinton, has ever drawn a salary from their work with the foundation. She added that that her work as secretary of state “was not influenced by outside forces.”

In an interview on Thursday night, Wikileaks founder Julian Assange fueled speculation that his organization is readying an “October surprise” document dump that could damage Clinton’s campaign.

He said Wikileaks is in possession of “significant” Clinton documents that work “unexpected angles” and would be published before November.
