The newest U.S. senator representing Utah was sworn into office Friday morning. Sen. John Curtis took the oath of office during a ceremony at the U.S. Capitol Friday, shortly after the 119th Congress convened. “Today, we start this new beginning,” Curtis said during a press conference Friday afternoon.

As a House member, John Curtis, R-Utah, exhibited a willingness to buck his own party. Now the senator-elect who is set to take the seat being vacated by retiring Mitt Romney, said he’s not afraid to disagree with President-elect Donald Trump if he needs to. In an exclusive interview on ABC’s “This Week,” Curtis told co-anchor Jonathan Karl that he wants Trump to be “wildly successful” and said he supports his desire to address inflation and the economy. But he also made clear there will be times he disagrees with Trump’s approach.

No one seemed to know what to do when John Curtis entered the Senate chamber. In the moments before, a steady stream of senators had shuffled in, taking their assigned seats. Mitt Romney, moments away from delivering his final Senate address, was already seated on the back row, his legs crossed, thumbing his cellphone. His colleagues, as they passed his desk, offered him greetings: Joe Manchin gave him a hug; Thom Tillis slapped his shoulder; Cory Booker cracked a joke.
