Which person is currently one of your state's U.S. Senators?

The current U.S. Senator from Indiana is Mike Braun. He has been serving in the Senate since January 2019, representing the state of Indiana. Senators are elected officials who serve six-year terms in the United States Senate, and each state has two senators. Mike Braun, a member of the Republican Party, focuses on various legislative issues relevant to Indiana and the nation.

In contrast, other individuals listed are not U.S. Senators from Indiana. Ron DeSantis is the Governor of Florida; Kamala Harris is the Vice President of the United States; and John McCain was a U.S. Senator from Arizona until his death in 2018. Hence, only Mike Braun is the correct answer in the context of Indiana's representation in the U.S. Senate.
