Lloyd Blankfein tweeted for the first time to lament Trump pulling out of the Paris Agreement

Goldman Sachs chief Lloyd Blankfein just fired off his first tweet.

The Wall Street CEO, using the handle @lloydblankfein, lamented President Trump's decision to pull out of the Paris Agreement.

He described the decision as a "setback for the environment and for the US's leadership position in the world."

The agreement, which 195 nations signed in December 2015, set a global goal to keep the planet from warming to a level that scientists say could keep the planet from launching into a tailspin of irreversible consequences.

Blankfein, a Hillary Clinton supporter, was asked whether he wished he had backed Donald Trump back in January.

"So, in hindsight, do you wish you had backed the other horse, then?" Joe Kernen of CNBC asked him in an interview at the World Economic Forum in Davos, Switzerland. "Or do you like more regulation and higher taxes?"

"But there's other things, there's other factors at work here, too," the Goldman Sachs CEO responded.

Blankfein isn't alone in corporate America in criticizing the move. Twenty-eight major US companies - including Apple, Gap, Facebook, Google, Microsoft, and Morgan Stanley - took out a full-page ad in The New York Times asking Trump to stay in the Paris agreement.

Both ExxonMobil and ConocoPhillips, two of the largest energy companies in the world, have also expressed support for the Paris accord.

General Electric CEO Jeff Immelt also tweeted his disappointment after Trump's announcement on Thursday.

"Disappointed with today's decision on the Paris Agreement," Immelt said. "Climate change is real. Industry must now lead and not depend on government."
