A spokeswoman for Republican presidential nominee Donald Trump said that Democratic presidential nominee Hillary Clinton has dysphasia, a form of brain damage (video below).
Katrina Pierson, who is not a doctor, made her diagnosis during an interview with MSNBC host Kristen Welker on Aug. 18.
Welker asked Pierson if Trump's strategy was to double-down on conspiracy theories about Clinton.
Pierson said that Trump had raised these theories during the GOP primaries, and it "really isn't anything new."
Pierson went on to recall how Trump has long-claimed that Clinton doesn't "have the strength or the stamina," an allegation that Trump has never proven.
"What’s new are the other reports of the observations of Hillary Clinton’s behavior and mannerisms ... as well as her dysphasia," Pierson stated. "The fact that she’s fallen, she has had a concussion, there are really interesting things out there," Pierson stated.
Pierson presented no medical evidence that Clinton suffers from dysphasia, which is a type of brain damage that impairs one's ability to speak or understand language, notes The Hill.
Welker then read a statement from Clinton's physician Dr. Lisa Bardack from Aug. 16:
As Secretary Clinton’s long time physician, I released a medical statement during the campaign indicating that she is in excellent health. I have recently been made aware of allegedly "leaked" medical documents regarding Secretary Clinton with my name on them.
These documents are false, were not written by me and are not based on any medical facts. To reiterate what I said in my previous statement, Secretary Clinton is in excellent health and fit to serve as President of the United States.
The fake documents Bardack referred to were confirmed as false by FactCheck on Aug. 16 in a detailed analysis that also noted the farcical claims have been spread by conservative media.
The claims about Clinton's supposed-ill health have appeared on Fox News and Infowars, a conspiracy website run by pro-Trump supporter Alex Jones.
Welker told Pierson that the health questions about Clinton have been "debunked," and added that "Donald Trump continues to try to stir them up."
"Is that responsible for someone who is running for president?" Welker asked.
Pierson said Trump was not referring to Clinton's actual health records, but rather "specific observations."
Welker cut off Pierson, telling her that Trump is "clearly trying to spin up some of that speculation" about Clinton's health.
Pierson insisted that Clinton's health is "something that needs to be addressed," and claimed she has "taken a lot of time off the campaign trail."
Pierson went on to say that Clinton, who has not held a press conference this year, should hold a press conference to answer questions about her health and a long list of non-medical questions.
Welker told Pierson that the press conference issue is being tracked by the news media, and added: "[Clinton] hasn't taken a lot of time off the campaign trail. I've been on the campaign trail with her, I'm one of the reporters covering her. She hasn't taken a lot of time off the campaign trail."
