Mr. Trump has previously said he does not believe systematic racism is a problem in the US.
A memo to government agencies says it has come to his attention that millions of dollars of taxpayers money have funded such trainings.
The documents says these sessions only foster resentment in the workforce.
The memo comes amid the social justice protests that have swept the nation in recent months.
The memo says that “According to press reports, employees across the Executive Branch have been required to attend trainings where they are told that virtually all White People contribute to racism or where they are required to say that they benefit from racism.”
“These types of trainings not only run counter to the fundamental beliefs for which out Nation has stood since its inception, but they also engender division and resentment within Federal workforce.”
It was not clear which reports Mr. Vought was referring to or what prompted the memo, but such trainings sessions have been highlighted by the Discovery Institute, a conservative non-profit think tank based in Seattle.
Chris Rufo, one of its research fellows, told this week that the US Department of Treasury is among federal agencies that have hired such trainers.
Mr. Rufo says his public records requests show these sessions have included teaching employees that White people uphold America’s system of racism, and sending white male executives to mandatory training in which they write letters of apology to minorities.
Joe Biden, who will challenge Trump for the White House in November, has vowed to fight systemic racism if elected.
In July, he said “For generations, Americans who are black, brown, Native American, immigrant, have not always been fully included in our democracy or our economy.”
