"The United States stands firmly... for preservation of the status quo with respect to holy sites in Jerusalem," White House Press Secretary Karine Jean-Pierre said.
"Any unilateral action that jeopardizes the status quo is unacceptable."
State Department spokesman Ned Price separately said the United States was "deeply concerned" by the visit of Itamar Ben-Gvir, who has a history of inflammatory statements and was given a key security position in Prime Minister Benjamin Netanyahu's latest government.
"This visit has the potential to exacerbate tensions and to provoke violence," Price said of the visit which was widely condemned in the Islamic world.
Price said the United States has had "direct conversations today with representatives of the prime minister's office regarding this visit."
