Republican John Kyl of Arizona, who served three terms in the Senate before retiring in 2012, was sworn in Wednesday to fill the seat left open by the death of Senator John McCain.
Kyl, 76, has only committed to serve until the end of the current congressional session on January 3, 2019.
Still, he'll have the chance to cast key votes, including on spending bills to keep the government running and whether to confirm Brett Kavanaugh to serve on the U.S. Supreme Court.
His support will give Republicans more cushion to confirm Kavanaugh before the midterm elections in November.
Republicans may also need his help on other Trump nominees.
Kyl was warmly greeted by senators from both parties as he entered the Senate chamber.
Vice President Mike Pence swore Kyl in while fellow Republican Sen. Jeff Flake stood by his side.
Kyl then walked over to McCain's old desk as colleagues applauded.
Senate Majority Leader Mitch McConnell said he could not be happier that the "new, not-so-junior senator" will be working during a time that he described as "all hands of deck for the American people."
He described Kyl as "one of the most serious, most expert, and most effective legislators with whom I've had the pleasure of serving."
