Roger Stone, a longtime adviser and ally of Republican presidential nominee Donald Trump, tweeted regarding Democratic presidential nominee Hillary Clinton and her purported health problems, “LOL Bitch can hardly stand up.” Trump has relied on Stone for conspiracy theories and research.

Stone tweeted the following during the early hours of October 25:

Hillary e-mail asked for medication for Parkinson’s Disease but libtards say I “made up “ her health problems. LOL Bitch can hardly stand up

— Roger Stone (@RogerJStoneJr) October 25, 2016

Stone has pushed numerous unfounded conspiracy theories about Clinton’s health, including that she was placed on an “oxygen tank” after a debate; was “hopped up on drugs” during the presidential debates; and is hiding from the public an “advanced form of epilepsy.”

The Republican consultant also regularly launches misogynistic smears against Clinton. In 2008, Stone established an anti-Clinton group called “C.U.N.T” (Citizens United Not Timid). He explained the name by claiming he spent “hours trying to come up with words for B.I.T.C.H. and just couldn't do it.”

Stone has also used misogynistic language against other women. He has tweeted that New York Times columnist Gail Collins is an “elitist c*nt,” MSNBC host Rachel Maddow is “Rachel the muff-diver,” Fox News’ Megyn Kelly has a “nice set of cans,” and that Rep. Debbie Wasserman Schultz (D-FL) is a “jap” (acronym for ”Jewish American Princess") who is “every man’s first wife.”
