Who serves as the representative for Utah House of Representatives District 1?

Rob Bishop is the correct choice as the representative for Utah House of Representatives District 1. He has held the office since 2013, representing this district in the U.S. House of Representatives. His role involves advocating for the interests of his constituents and participating in the legislative process at the federal level.

The other names mentioned are prominent figures in Utah's political landscape, but they do not serve in the House of Representatives. Orrin Hatch was a long-serving U.S. Senator from Utah until his retirement in 2019. Mitt Romney and Mike Lee are also U.S. Senators, representing Utah in the Senate alongside their responsibilities on various committees and national issues. Therefore, Rob Bishop is the correct representative for the specified House of Representatives district.
