Treasury Secretary Steven Mnuchin may be new to government, but he's learning quickly that it's not a good idea to make a joke that could run afoul of government ethics rules.
In a letter Friday to the head of the Office of Government Ethics, Mnuchin says it was a mistake for him last week to jokingly urge parents to send their kids to see "The Lego Batman Movie." Mnuchin was an executive producer of the top-grossing movie, which is still in theatres.
Mnuchin said his comment, which came at the end of an hour-long public interview sponsored by the news site Axios, was meant as a joke in response to a light-hearted question about what current movies he would recommend.
