A state director for Donald Trump's presidential campaign said that Hillary Clinton is not healthy, and is highly likely to die during her first year in the White House.

John Jaggers, the Maryland and Northern Virginia state director for Trump's campaign, made the comments at a "Moms 4 Trump" rally in Virginia over the weekend.

"How many of you would wear a wool coat in August?" Jaggers said to the crowd at the Salamander Resort in Middleburg, Va. "The woman who seeks to be the first female president of the United States wears a wool coat at every single thing. Have you ever stopped to wonder why?"

Jaggers then connected the wool coat wearing to Clinton's failing health, something several other Trump supporters and surrogates suggested in recent weeks.

"It's a big deal, folks. This woman is very, very sick and they're covering it up. You're not so much talking about Hillary Clinton being president for eight years, you're talking about Tim Kaine being president for eight years. Because that's what we're dealing with here," Jaggers said.

The Clinton campaign has dismissed attacks on the Democratic nominee's health.

"Donald Trump is simply parroting lies based on fabricated documents promoted by Roger Stone and his right-wing allies," Jennifer Palmieri, Clinton's communication director, said over the weekend. "Hillary Clinton has released a detailed medical record showing her to be in excellent health plus her personal tax returns since 1977, while Trump has failed to provide the public with the most basic financial information disclosed by every major candidate in the last 40 years. It's time for him to stop using shameful distractions to hide his own record."

Clinton's doctor, Dr. Lisa Bardack, has also released a statement saying the 70-year-old former secretary of state "is in excellent health."
