The Trump campaign finance chief Steve Mnuchin, who is Jewish, has been selected to serve as Treasury Secretary.
Mr Mnuchin, 53, made his fortune as a banker for Goldman Sachs, and has also produced the blockbuster films Avatar and X-Men, among others.
Meanwhile, more than 600 rabbis and cantors across the US signed a pledge this week to hold the Trump administration accountable for protecting the human rights of all people.
It read: "Jewish history has taught us that fascism arrives slowly, through the steady erosion of liberties. And we have learned that those who attack other minorities will eventually come to attack us."
The Southern Poverty Law Center, a hate watchdog, reported that hate crime in the US had soared, with 867 incidents occurring in the 10 days following the election of Donald Trump. Around 100 were classified as antisemitic.
