Al Sharpton got a surprise phone call Thursday morning — from President-elect Donald Trump.

The civil rights preacher, who was convening a meeting of his National Action Network board of directors, said Trump called out of the blue.

“We did talk briefly. I was surprised and candid about our sharp disagreements and so was he,” Sharpton said.

A sharp Trump critic during the campaign, Sharpton said it’s important to have a dialogue with political foes to try to find common ground.

“He met with Mayor [Bill] de Blasio, who is critical, like I am, of him,” he said.

Sharpton said Trump thanked him for saying nice things about his outer-borough business achievements while on MSNBC’s “Morning Joe” program.

Sharpton has attacked Trump for attempting to undermine President Obama’s presidency by questioning whether Obama was even born in the US.

Sharpton also vowed to fight Trump’s push to repeal the Affordable Care Act.
