The billionaire businessman, Warren Buffett, has defended the Giving Pledge, a movement that requires billionaires to pledge to donate significant amounts of their wealth to worthy nonprofit organizations in their lifetime. Despite recent conservative backlash, Buffett remains committed to the initiative. PayPal co-founder Peter Thiel, who has aligned with the Trump administration, reportedly urged Elon Musk to renege on his 2012 commitment, claiming his money would support "left-wing nonprofits".
