Trump's son Eric Trump spreads false video clip claims that Democrat presidential candidtate Joe Biden had been “caught red-handed using a teleprompter.”

A video of Joe Biden answering live questions during a television interview is being edited to claim, incorrectly, that the Democratic presidential nominee was using a teleprompter.

In the full interview with Telemundo, conducted Sept. 15, Biden can clearly be seen looking to his left, where the television studio set up a screen with live incoming questions from voters. An edited version of the video shows just one moment where Biden was unable to view a question and says, “I lost that line.”

The 26-second clip from the video has been shared by people close to President Donald Trump, including his son Eric Trump, who tweeted Wednesday that Biden had been “caught red-handed using a teleprompter.” Trump’s campaign also ran an ad amplifying the false claim against Biden.

A Telemundo spokesperson said Wednesday that recent social media posts claiming that Biden used a teleprompter during an interview with Noticias Telemundo and anchor Jose Diaz-Balart were false.
