Senate Democrats encouraged President Trump to remain a part of the Paris Climate Agreement during a press conference on Wednesday.
The White House says the president has not made up their mind about staying in the agreement, but Senate Minority Leader Sen. Chuck Schumer, D-New York, said that the Trump administration is "leaning towards withdrawing the United States" from the pact.
In anticipation of the Group of Seven (G7) conference in Sicily this week, which will be President Trump's first appearance at an international summit, 40 Senate Democrats signed and sent a letter to the president urging him not back out of the international climate change agreement.
The agreement was signed last year during Barack Obama's presidency at the COP21 conference in Paris, where nations committed to slowing the effects of climate change through cutting down on greenhouse gas emissions.
Earlier in May, Mr. Trump delayed a meeting on the Paris Climate Agreement, citing "scheduling conflicts" for the postponement. The White House has said the president will announce the United States' position on the agreement after the G7 conference.
