The Donald Trump campaign really wants you to believe that Hillary Clinton, at 68, has one foot already in the grave.

For weeks, 70-year-old Trump and his surrogates have been hinting that something might be wrong with the Democratic nominee's health and in recent day those hints have turned into a full-on public campaign to raise doubts regarding Clinton's physical fitness for the presidency.

Trump remarked at an Iowa rally early this month that Clinton was, "actually not strong enough to be president." His surrogates have been on the attack since. Trump spokeswoman Katrina Pierson, in an interview with MSNBC Thursday, alleged that Clinton has dysphasia, a condition Pierson says was brought on by brain trauma that impairs the former Secretary of State's ability to speak. In an appearance on "Fox News Sunday," former New York City mayor and Trump adviser Rudy Giuliani became the most high-profile surrogate to make comments about Clinton's health.

"She has an entire media empire that constantly demonizes Donald Trump and fails to point out that she hasn't had a press conference in 300 days, 200 days, 100 days, I don't know how long. Fails to point out several signs of illness by her," he told anchor Shannon Bream.

When Bream pushed Giuliani to expound, he added, "Go online and put down 'Hillary Clinton illness,' take a look at the videos for yourself."

The top YouTube result for "Hillary Clinton illness" is a video titled, "Hillary Clinton 'NEURO-LOGICAL 'DISORDER'' EXPOSED!!!!" The 21-minute video, which splices together news reports about Clinton's concussion in 2012 and blood clot in 2013, has 246,402 views and also features claims that Clinton had a DNC staffer killed and is surrounded by "Illuminati handlers."

Secret societies aside, it seems the conspiracy theories regarding Clinton's health began in conservative corners of media after she experiences a brief period of illness in late 2012 and early 2013. Clinton, who was then still Secretary of State, passed out from flu-related dehydration while traveling and hit her head, sustaining a concussion. That concussion led to blood clot between her brain and skull. Clinton was ultimately treated with blood thinners and given a clean bill, but that hasn't been enough to silence her skeptics.

If Trump is interested in an expert view of Clinton's health, however, he can always consult her doctor. Hillary Clinton's longtime physician Lisa Bardack released a two-page letter summering Clinton's health last fall that literally described her as "in excellent physical condition and fit to serve as President of the United States."

If that's not enough, he should watch her open a jar of pickles with Jimmy Kimmel.
