Donald J. Trump called Jamie Dimon “overrated” in a typically over-capitalized post on his Truth Social outlet Thursday, The Hillreports, over the JP Morgan Chase CEO’s support for former South Carolina Gov. Nikki Haley’s run for the GOP presidential nomination. 

Following Americans for Prosperity’s endorsement of Haley, who also was UN ambassador in the Trump administration, Dimon said Democrats should help her candidacy, saying she would be “better than Trump.”

“Highly overrated globalist Jamie Dimon, the CEO of JP MORGAN, is quietly pushing another non-MAGA person,” Trump posted. “I’ve never been a big fan of Jamie Dimon, but had to live with this guy when he came begging to the White House.”
