Donald Trump shouldn't expect a sleep-over invitation from Mitt Romney anytime soon.

The 2012 GOP presidential nominee remarked Saturday at a Fourth of July parade in  Wolfeboro, New Hampshire, that Trump's comments about Mexican immigrants have hurt the Republican Party, as reports CNN.

Romney was specifically asked by an individual at the event if the business mogul's assertion that Mexican immigrants to the U.S. are criminals and "rapists" has done damage to the GOP, to which he replied in the affirmative.

"I think he made a severe error in saying what he did about Mexican-Americans," Romney explained.

When asked whether 2016 GOP candidates should address Trump's statements, Romney commented, "I think a number of them have."

During his speech announcing his candidacy for president, Trump said on the topic of illegal immigration, "When Mexico sends its people, they're not sending their best. They're not sending you. They're not sending you. They're sending people that have lots of problems and they're bringing those problems with us. They're bringing drugs, they're bringing crime, they're rapists, and some, I assume, are good people."

While some Republicans -- like presidential candidate Texas Sen. Ted Cruz -- have indicated approval of Trump's statements, others -- 2016 contender former New York Gov. George Pataki, for example -- have denounced them.

Romney also said Saturday that he is not yet prepared to endorse a single GOP candidate for the nomination despite the fact that he and candidates New Jersey Gov. Chris Christie and Florida Sen. Marco Rubio slumbered together at Romney's summer home in the area Friday night before attending the New Hampshire event.

"A lot of these folks helped me during my campaign," Romney explained. I'm going to be as loyal to them as they were to me."
