Hillary Clinton received the questions for the third presidential debate ahead of time, Donald Trump appeared to claim Thursday ― without offering any evidence, of course.

Why didn't Hillary Clinton announce that she was inappropriately given the debate questions - she secretly used them! Crooked Hillary. — Donald J. Trump (@realDonaldTrump) October 20, 2016

Although the GOP nominee didn’t specify which debate he was referring to, the timing of the tweet suggested he was speaking about Wednesday’s debate at the University of Nevada, Las Vegas.

The event was moderated by Fox News host Chris Wallace. The prospect of the conservative network “rigging” the debate in Clinton’s favor is laughable. Wallace was widely praised for his fine job of focusing on the issues, and he pressed both candidates equally.

His fear of a rigged debate seems to stem from a hacked WikiLeaks email that suggested that Donna Brazile, the interim chair of the Democratic National Committee, earlier this year shared the text of a proposed question with Clinton ahead of a CNN town hall event featuring her primary opponent, Sen. Bernie Sanders (I-Vt.).

Reached for comment on Thursday, a Fox News spokesperson said Trump appeared to have been speaking about the Democratic primary town hall and noted his campaign manager, Kellyanne Conway, even praised Wallace for his “fantastic” job moderating the debate.

Editor’s note: Donald Trump regularly incites political violence and is a serial liar, rampant xenophobe, racist, misogynist and birther who has repeatedly pledged to ban all Muslims — 1.6 billion members of an entire religion — from entering the U.S.
