repeatedly used Russian propaganda in his campaign ads?

In one instance, a Trump advertisement saying to support the troops used footage of Russian jets.

In another, Trump’s campaign used footage from Russian factories and Ukrainian companies.

During the Republican National Convention, in another video railing against riots in US cities after the death of George Floyd at the hands of police, footage was used from protests in Spain.

Another advertisement featured a Philadelphia woman and her business. She says she was misled by the filmmakers and only learned about it being used for a political advertisement when she saw it on television.

Similarly, Dr. Fauci said his words were used out of context and without permission in another advertisement.

Other advertisements also used stock footage and misleading content, including boxes labelled “MADE IN USA” and championing job growth while showing footage of an Illinois steel plant that had laid off hundreds of workers.
