WASHINGTON (CNN/CBS) — President Donald Trump announced from the White House Rose Garden Thursday that the United States is withdrawing from the Paris climate accord, a major step that fulfills a campaign promise while sparking global outcry.

“Therefore, in order to fulfill my solemn duty to protect America and its citizens, the United States will withdraw from the Paris climate accord,” Trump said.

The president said that he will begin negotiations to re-enter the Paris accord or an entirely new transaction “with terms that are fair to the United States.”

Trump called the agreement “draconian.”

“This agreement is less about the climate and more about other countries gaining a financial advantage over the U.S.,” Trump said.

Following Trump’s speech, Germany, Italy and France said in a joint statement that the accord will not be renegotiated.

The White House began informing members of Congress Thursday afternoon that Trump planned to pull out of the U.S. from the landmark agreement, according to a congressional source.

In talking points delivered to Trump’s allies, the White House characterized the Paris agreement as a job killer that placed undue burdens on American taxpayers.

“The Paris Accord is a BAD deal for Americans, and the President’s action today is keeping his campaign promise to put American workers first,” the talking points read. “The accord was negotiated poorly by the Obama administration and signed out of desperation. It frontloads costs on the American people to the detriment of our economy.”

Trump and Vice President Mike Pence were calling lawmakers, including House and Senate leaders, in the hours leading up to the announcement to get input on his climate decision, a Republican source said.

In triggering the official withdrawal process, Trump will spark a lengthy process that won’t conclude until November 2020 — the same month he’s up for re-election.

The president campaigned against the climate agreement as a candidate, and those close to him suggest he’s ready to fulfill those promises to remove the U.S. from the 195-country deal. The move would isolate the U.S. in a global effort to curb the warming of the planet, and leave an opening for countries like China to fill the leadership void.

The U.S. is now one of three countries that are not taking part in the deal. The other two are Syria and Nicaragua.

Pressure to remain in the Paris accord has been intense, however, including from some of Trump’s closest aides.

But a person familiar with Trump’s thinking said the president was convinced he needed to withdraw from the pact, and there was little chance of talking his out of it.

Trump, a former reality star himself, advertised the announcement in a tweet late Wednesday. Earlier in the day, he told reporters he was “hearing from a lot of people both ways.”

On Thursday morning, senior administration officials would not reveal the precise mechanism the U.S. would utilize to execute the decision.

Trump would have several options, including triggering a years-long withdrawal process or taking the more drastic step of removing the U.S. from the United Nations climate treaty. He could also declare the Paris agreement a treaty that requires Senate approval, which isn’t likely to come from the Republican-controlled body.

Lawyers and other administration aides have planned a withdrawal announcement, but recognize Trump has changed his mind at the last minute previously on important decisions where outside forces are pressuring him to moderate his position.

As news emerged Wednesday that Trump planned to quit the Paris deal, business leaders and foreign heads-of-state began castigating the decision as a woeful abandonment of US leadership. Elon Musk, the chief executive of Tesla, said he would resign from White House business councils if Trump followed through.

Apple CEO Tim Cook also urged Trump to reconsider.

Inside the West Wing, attempts to sway Trump’s thinking also continued apace. Trump’s daughter and senior adviser, Ivanka, has worked to ensure her father heard pro-Paris voices over the last several months, and has continued to press for a decision short of a full withdrawal.

Ivanka Trump and her allies, including Secretary of State Rex Tillerson and Trump’s chief economist Gary Cohn, have pressed Trump to alter the U.S. commitments to the Paris agreement without fully pulling out of the accord.

A Republican familiar with Trump’s decision-making said the expected announcement could include some attempts to satisfy his daughter’s point of view, but didn’t specify what that might include.

But anti-Paris voices, led by chief strategist Steve Bannon and EPA administrator Scott Pruitt, have appeared to won out. In conversations with his advisers, Trump has cited the affect a withdrawal would have on the states where he won by the largest margins, including in the Rust Belt and the western plains.

That’s a reflection of Trump’s “America First” governing policy, which he’s sought to bolster since taking office. Trump was pressured heavily by his foreign counterparts during last week’s G7 meetings in Sicily to remain in the deal, but his advisers say he felt little obligation to concede to that point of view.

On Wednesday, global figures began reiterating their own commitment to the Paris deal as Trump prepared to withdraw. Chinese premier Li Keqiang, visiting Germany, said his country would remain committed to combating climate change, despite US moves.

And European Commission President Jean-Claude Juncker declared Europe was ready to act as a global climate leader in the US absence.

“The vacuum that would be created has to be filled, and Europe has aspirations for a natural leadership in this whole process,” he said in Berlin.
