Trump's campaign has tried to paint Biden and Harris as a "Trojan horse" for the "radical agenda".
Last month, Harris was asked on CBS about Trump's comments and if she would push those policies "from the left wing of the Democratic party".
Harris responded: "“I am not going to be confined to Donald Trump’s definition of who I or anybody else is and I think Americans learned that would be a mistake."
In the same interview, she burst out laughing when asked if she would advocate for a “socialist or progressive perspective” if elected.

If Biden were to resign during his term, then Harris would automatically ascend to Commander-in-Chief.
However, he could removed from office under the 25th Amendment to the US Constitution.
A sitting president can be removed from office if the vice president and a majority of the cabinet determine that he or she is “unable to discharge the powers and duties” of the office.
Should that happen, the vice president would immediately assume the office of president.
Harris was a presidential candidate last year, the former district attorney of San Francisco and is a current Senator for California.
Harris has been married to her husband Douglas Emhoff, a lawyer, for the past six years and has two step-children, Ella and Cole.
