Former GOP presidential nominee Mitt Romney on Tuesday changed his Twitter location to Utah, amid speculation that he could run for the state’s Senate seat in 2018 following Sen. Orrin Hatch’s (R-Utah) announcement that he’s retiring. 

Romney, who’s also a former Massachusetts governor, changed the location in his Twitter bio from “Massachusetts” to “Holladay, Utah,” where he owns a house. 

Bloomberg reporter Sahil Kapur first flagged the change.

Hatch, 83, announced Tuesday he would not seek reelection to the Senate in 2018, ending a career that lasted four decades.

Romney has reportedly met with top Senate Republicans in preparation for a possible campaign for the seat, but has not publicly declared his future political plans. Until Tuesday, Hatch had hinted at a possible 2018 run. 

Romney praised Hatch in a statement posted to Facebook following the senator’s announcement. 

“As chairman of the Senate Finance and Judiciary Committees and as the longest-serving Republican senator in US history, Senator Hatch has represented the interests of Utah with distinction and honor,” Romney said. “Ann and I wish Senator Orrin Hatch and his loving wife Elaine all the best in their future endeavors.”
