Twitter user Aaron Rupar shared the seven second clip of the 36-year-old, highlighting that the arena holds a lot less than claimed.
"Eric Trump just claimed that "my father had 30,000 in an arena in Charlotte last night." (The Bojangles Center in which the rally was held holds 8,600 people.)" said Mr Rupar.
This is not the first time that the Trump family have lied about the number of attendees at an event or rally.
Then, last year the US President was publicly called out by a fire department in El Paso, Texas, after he claimed in his speech that fire department officials helped him get 10,000 people into his rally.
The coliseum only holds around 6,500 people and Enrique D Aguilar, a spokesperson for the department denied Mr Trump was given special permission, telling the El Paso Times “It might be 10,000 with the people outside,".
Last year, The Washington Post's Fact Checker database claimed that the US President averages 22 lies and inaccuracies every day.
