Hillary Clinton blasted Donald Trump as “reckless” on foreign policy and for failing to understand how the federal government runs.

Trump doesn’t grasp that the skills needed to govern differ from those in running a business, she said in an interview with CBS' Face the Nation broadcast on Sunday.

“Maybe he just doesn't understand that running our government is not the same as making real estate deals,” said Clinton, the likely Democratic nominee.

Clinton, who has a virtually insurmountable lead over Vermont Sen. Bernie Sanders in her bid for the nomination, took Trump to task for comments he has made on foreign policy and national security.

Trump has floated the possibility of allowing Japan and South Korea to obtain nuclear weapons. Such “cavalier” comments about nuclear weapons, Clinton said, were “reckless and dangerous.”

Clinton also criticized Trump for his suggestion that the U.S. target the families of terrorists.

“Those are war crimes,” Clinton said.

On domestic policy, Clinton said she and Sanders agreed on “reining in bad actors” on Wall Street and raising the minimum wage. Trump, on the other hand, “doesn’t have a view, he has a slogan.”

Clinton also said she hopes the FBI probe of her use of a private email server during her tenure as secretary of State would be “wrapped up soon," and acknowledged it had been a mistake.

“I always took classified material seriously,” she added.
