President Donald Trump is pressing to settle the U.S. position on the Paris Agreement on climate change before his first overseas trip later this month.

White House officials were expected to close an internal debate on whether the U.S. should withdraw or take more measured steps, but a key meeting on the matter scheduled for Tuesday was postponed at the request of Secretary of State Rex Tillerson, who would have been unable to attend, an administration official said.

Two weeks after his electoral victory in November, Mr. Trump said he had “an open mind” about the agreement by 190 countries aimed at combating climate change, reversing his campaign pledge to withdraw completely. But after softening campaign positions on China and NATO in recent weeks, the president may be looking to rebalance his approach on the world stage with a major move reaffirming his “America First” principles.

The faction for withdrawing completely is led by EPA Administrator Scott Pruitt, senior adviser Steve Bannon and White House counsel Don McGahn, several officials said. They are eager for the decision to come ahead of the G-7 and G-20 summits later this month in Italy and Germany, respectively, where world leaders are likely to pressure Mr. Trump to stay in the agreement.

France’s president-elect, Emanuel Macron, urged Mr. Trump not to dismantle the Paris accord during a congratulatory phone call Monday, his spokesman told CNN.
