Romney reportedly began informing GOP insiders of his intentions last month, and Hatch has frequently said that Romney is his personal choice for the seat.
"There's no question that he loves Utah and wants to support Utah any way he can. And I'm hopeful he'll run, because he would be just fine," Hatch said in January.
"And he would certainly be somebody who I think could succeed me into the job. We haven't spoken in the last few days, but if Mitt decides to run, he knows he'll have my support."
The move has also garnered support from other Senate Republicans, who are reportedly eyeing Romney to take over leadership of the National Republican Senatorial Committee (NRSC).
Romney congratulated Hatch on his long career in the Senate in a Facebook post last month.
"I join the people of Utah in thanking my friend, Senator Orrin Hatch for his more than forty years of service to our great state and nation," Romney wrote.
"As Chairman of the Senate Finance and Judiciary Committees and as the longest-serving Republican Senator in U.S. history, Senator Hatch has represented the interests of Utah with distinction and honor," he continued.
