Republican presidential nominee Donald Trump has unleashed a torrent of falsehoods during his campaign, spanning a wide range of issues. His disregard for the facts was a prominent feature of the first presidential debate. Trump is heavily lying again during the second presidential debate, and journalists and media outlets are calling him out on Twitter:

Trump Claims Clinton's Campaign Started The Birther Movement

Trump On San Bernardino

Trump On Iraq

Trump Claims U.S. Is The Highest Taxed Nation

Trump On Syrian Refugees

“Many people saw the bombs all over the apartment in san bernardino.” A complete and total lie. Never happened.

“Many people saw the bombs all over the apartment” in San Bernardino. This is one of the baldest lies Trump has told on the debate stage.

— Brian Stelter (@brianstelter) October 10, 2016

There is NO evidence that there were bombs all over the apartment of the San Bernardino shooters. Trump just casually says that all the time

— Sam Stein (@samsteinhp) October 10, 2016

That is just a lie that many people saw the bombs in San Bernadino. It's slander against Muslims.
