At tonight's final presidential debate in Las Vegas, NV, Trump's penchant for lying is again on display.

— Katy Tur (@KatyTurNBC) October 20, 2016

Trump claims he didn't say other nations should get nukes. “You're not going to find a quote from me.”

Here it is: https://t.co/Rgmn5BcuUz

This is where the moderator should fact-check. Trump TOLD Chris Wallace in interview that maybe Japan would be better off with nukes https://t.co/P4WMz8fUHV

Here are the quotes Trump just said you will never find: https://t.co/Lrr1FwHYT6 “It could mean nuclear.”

— Josh Rogin (@joshrogin) October 20, 2016

Trump saying that Hillary will DOUBLE your taxes is the biggest debate lie yet. Bottom 99% would be almost unchanged. pic.twitter.com/Nlk2ZYcrcE

HRC's tax plan will not double anyone's taxes unless they are very wealthy and pay very little in taxes.

— Nick Riccardi (@NickRiccardi) October 20, 2016

HRC's plan is not going to double anyone's taxes.

— Ray Locker (@rlocker12) October 20, 2016

Trump says Clinton plan is “going to double your taxes.”

Trump Lies About $6 Billion Going Missing From Clinton's State Department

Trump said the State Department lost $6 billion under Clinton. That would be a lie: https://t.co/GoLUcU6fBI

— Pat Garofalo (@Pat_Garofalo) October 20, 2016

It is false that $6 billion went missing at State. The inspector general just said that the documentation of the contracts was missing.

— Daniel Dale (@ddale8) October 20, 2016

The inspector general who did the investigation said flatly that $6 billion was not missing from the State Department.

Trump Pretends He Didn't Belittle His Accusers As Unattractive (He Did, Repeatedly)

Here is Trump talking about the unattractiveness of one of his accusers five days ago in North Carolina, which he just denied ever doing: pic.twitter.com/lKMu4WtMPR

Trump absolutely did say he couldn't have assaulted those women bc they were unattractive. Come on. We've all seen the clips.

— Jonathan Merritt (@JonathanMerritt) October 20, 2016

Trump denies he said his accusers were too unattractive to assault. “I did not say that.”

He did: https://t.co/8nAiwhK3Tl

— Pat Garofalo (@Pat_Garofalo) October 20, 2016

Fact-check: Trump did, in fact, insult the looks of the women who accused him of sexual assault. https://t.co/KKjl9eUDbS

— Ben Adler (@badler) October 20, 2016

Trump now lying, brazenly, by saying he didn't make the women's looks an issue.

Trump's Makes Outlandish Claims About Voter Fraud
