Former New York City Mayor Rudy Giuliani on Monday continued to insist that Hillary Clinton's physical and mental health is failing but again offered no evidence beyond unsubstantiated or debunked theories circulating on the Internet.
Over the weekend, Giuliani, who is a close adviser to GOP nominee Donald Trump, urged people to look for videos on the Internet that support such theories. "Go online and put down 'Hillary Clinton illness,' take a look at the videos for yourself," Giuliani urged on "Fox News Sunday."
Clinton's campaign later shot back on Twitter, suggesting people "Google Rudy" to read about why he withdrew from the 2000 Senate race, which was directly linked to his health.
But Giuliani doubled down on Monday morning on Fox News, saying that Clinton is "tired" and recently "looked sick."
The attack on Clinton's health has come back into focus in recent weeks, with conservative media outlets fueling speculation by offering up old photos and debunked reports, such as Clinton faking medical records or false accusations that she has a defibrillator.
Fox News' Sean Hannity, Dr. Drew and pharma executive Martin Shkreli are among those who have intensified the conspiracies. A YouTube video made by an InfoWars writer earlier this month—which now has over 3 million views—claims Clinton has a plethora of diseases, including autism and a brain tumor.

Trump himself has ventured into the topic, saying in the midst of a foreign policy speech last week that Clinton "lacks the mental and physical stamina to take on ISIS." Trump campaign spokesperson Katrina Pierson took it upon herself to diagnose Clinton with "dysphasia," a brain impairment. And the candidate has alluded to Clinton's failing health on the campaign trail, saying that she'll often "disappear" after giving a speech, presuming she "goes home and goes to sleep."
Asked to explain the attacks on Clinton's health, Trump campaign manger Kellyanne Conway said "I'm not a doctor" in a recent MSNBC interview with Chris Matthews.
After initially ignoring the attacks, the Clinton campaign last week responded to the speculation, resurfacing a medical note from Clinton's physician from last summer, which concluded that she was healthy.
The same doctor, Lisa Bardack, responded to the rumors and doctored medical records, decrying the documents as false.
"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," Bardack said.
The campaign in statement attacked Trump for pushing "deranged conspiracy theories" during his foreign policy speech, in a "desperate attempt t change the subject—this time with absurd and debunked claims about Hillary Clinton’s health."
