Republican U.S. Sen. Joni Ernst is scheduled to give the GOP response to President Barack Obama’s sixth State of the Union address Tuesday night. The freshman senator is expected to address controversial proposals the president will outline in his speech, such as tax hikes for the wealthy. Ernst also is likely to call on Obama to work with the GOP-controlled Congress in 2015 rather than act unilaterally, in light of his recent executive actions on U.S.-Cuba relations and the nation’s immigration system.

“I am truly honored to deliver the Republican address. It’s a long way from Red Oak, Iowa, to Washington, D.C. But now that I am here, I am excited to get to work in order to craft and implement real solutions as we chart a new path forward for our great nation,” the former Iowa state senator said in a statement posted on the House Republicans' official Facebook page.

Ernst became the first woman from Iowa elected to Congress. Her midterm election victory in November helped the GOP take control of the U.S. Senate for the first time since 2006. She has been called a rising star in the Republican Party since House Speaker John Boehner and Senate Majority Leader Mitch McConnell announced their pick last week to deliver the Republican address to the nation. Former Virginia Gov. Bob McDonnell, who recently was sentenced to two years in prison for public corruption, gave the GOP response in 2010.

The GOP live stream will begin immediately after the State of the Union address, which is scheduled for 9 p.m. EST. Watch Ernst deliver the Republican response here:
