Which of the following is a current U.S. Senator from Utah?

Mitt Romney is a current U.S. Senator from Utah, having been elected to the Senate in 2018. His role as a senator involves representing the interests of Utah residents at the federal level, participating in legislative processes, and addressing national issues while considering the specific needs and concerns of his state.

The other options are notable figures in U.S. politics, but they represent different states or political affiliations. Bernie Sanders is an independent senator from Vermont, Chuck Schumer is a senator from New York and the Senate Majority Leader, and Lindsey Graham is a senator from South Carolina. Each of these senators has their own legislative priorities and duties, but none holds the position representing Utah in the Senate like Mitt Romney does.
