Vice President-elect Kamala Harris has echoed Biden's remarks that the Capitol protesters were treated differently to those in the Black Lives Matter demonstrations.
"We witnessed two systems of justice when we saw one that let extremists storm the United States Capitol, and another that released tear gas on peaceful protesters last summer," she said.
"The American people have expressed outrage, rightly. We know this is unacceptable. We know we should be better than this."
Harris said in the US justice system, there are differences in how people are treated depending on their race and wealth.
She said the public servants that will be a part of the Biden administration will "help to ensure all Americans are treated equally".
