2012 Republican presidential nominee Mitt Romney on Wednesday expressed his support for the U.S. to remain in the Paris climate accord, arguing it was an opportunity to remain a leader on the world stage.

“Affirmation of the Paris Agreement is not only about the climate: It is also about America being the global leader,” Romney tweeted.

Romney’s tweet comes after reports surfaced Wednesday that President Trump would pull out of the 195-nation deal negotiated under former President Barack Obama Barack Hussein ObamaObama warns of a 'decade of unfair, partisan gerrymandering' in call to look at down-ballot races Quinnipiac polls show Trump leading Biden in Texas, deadlocked race in Ohio Poll: Trump opens up 6-point lead over Biden in Iowa MORE in 2015.

Pulling out of the agreement would be a dramatic reversal from the Obama administration’s stance on the deal.

Several figures in the administration have pushed for Trump to remain in the agreement, including top White House advisers Gary Cohn and first daughter Ivanka Trump.

Romney, a former governor of Massachusetts, also joins Secretary of State Rex Tillerson in favoring the U.S. staying in the agreement.

Romney was considered for the position of secretary of State late last year, before Tillerson was ultimately picked.

Trump tweeted Wednesday he would be announcing his final decision on the agreement in “the next few days.”
