Major business leaders, particularly Netflix CEO Reed Hastings, knocked Republican presidential candidate Donald Trump as part of a statement released by Hillary Clinton's campaign Thursday. The announcement also included a lengthy list of supporters including Warren Buffett of Berkshire Hathaway, Facebook COO Sheryl Sandberg and Alphabet Executive Chairman Eric Schmidt.

"Trump would destroy much of what is great about America. Hillary Clinton is the strong leader we need, and it's important that Trump lose by a landslide to reject what he stands for,"Hastings said in a statement from the Clinton campaign.

Dan Akerson, who has served as a naval officer as well as CEO of General Motors, said he will vote for Clinton, despite having consistently voted for Republican candidates in the past.

"Serving as the leader of the free world requires effective leadership, sound judgment, a steady hand and most importantly, the temperament to deal with crises large and small. Donald Trump lacks each of these characteristics," Akerson said. "Hillary Clinton has the experience and judgment to serve as an effective commander in chief."

Mark Pincus, co-founder of Zynga, said Clinton has a "proven record of fighting for the American people ... [who] need an advocate, not an opportunist."

"Donald Trump has failed to put forth concrete and realistic policies to help the American people and grow the economy. Our president must care about the success of the country as a whole — not just himself," Pincus said.

Other Clinton backers took the opportunity to criticize Trump and his behavior. Erroll Davis, former chancellor of the University System of Georgia, praised Clinton's temperament and experience.

"Her ability to work with other democratic leaders stands in stark contrast to Donald Trump's continued praise of authoritarian figures and support for dangerous and erratic policies," Davis said.

Earvin "Magic" Johnson, chairman and CEO of Magic Johnson Enterprises, also endorsed Clinton, saying "her decisiveness, pragmatism and calm demeanor stand in absolute contrast to Trump."

Some in the business community have backed Trump including billionaires like investor Carl Icahn, Home Depot co-founder Ken Langone and distressed asset investor Wilbur Ross.

A spokeswoman for the Trump campaign did not immediately respond to CNBC's request for comment.
