U.S. Senator John Curtis, a Latter-day Saint representing Utah, called Tuesday for an investigation into the business dealings of presidential family members, citing recent criticism of Donald Trump Jr.'s activities, according to the Salt Lake Tribune.

Curtis, a Republican, said presidential relationships should not be used to benefit family members financially. The statement represents a notable Republican criticism of the Trump family's business practices during the administration.

The Mormon connection is Curtis himself: he is one of several LDS senators from Utah and his positions are closely watched in a state where the Church's membership is politically influential. Curtis has at times broken with party leadership on Trump-related issues.
