Former Education Secretary Bill Bennett blasted Mitt Romney Wednesday on "The Story," criticizing the incoming Utah senator for his scathing opinion piece about President Trump.

Romney, the 2012 Republican nominee for president, wrote that Trump "has not risen to the mantle of the office."

He wrote that with such a "divided, resentful and angry" nation, the president seemingly has lacked the leadership needed to resolve it.

Bennett, a Fox News contributor, said that Romney's criticisms of Trump were shameful.

"It was a gratuitous, unnecessary, and ill-timed shame," he told Sandra Smith. "Shame on Mitt Romney for doing it."

He added that if Romney decides to run again for president, he'd come out unsuccessful.

"I don't understand the timing [of the op-ed]. The man is not even sworn-in yet," Bennett said, adding that when Romney was running for senator in Utah, he didn't bring up his criticisms against Trump.

In an interview Wednesday, Romney defended his remarks and also said he has not decided who he'll endorse in 2020.

"What team are you on, Sen. Romney?" Bennett asked. "Didn't you run as a Republican? ... Has Mitt Romney played team sports? Does he understand anything about the situation that his Republican colleague, Donald Trump, is in now?"
