RALEIGH, N.C. (AP) — A defensive Donald Trump gave Hillary Clinton plenty of fresh material for the next phase of her presidential campaign on Tuesday, choosing to publicly reopen and relitigate some her most damaging attacks.

The day after his first general election debate, Trump blamed the moderator and a bad microphone and said he was holding back to avoid embarrassing Clinton. Next time, he threatened, he might get more personal and make a bigger political issue of former President Bill Clinton’s marital infidelities.

Things are already getting plenty personal. On Monday night, Trump brushed off Clinton’s debate claim that he’d once shamed a former Miss Universe winner for her weight. But then he dug deeper the next day — extending the controversy over what was one of his most negative debate night moments.

“She gained a massive amount of weight. It was a real problem. We had a real problem,” Trump told “Fox and Friends” about Alicia Machado, the 1996 winner of the pageant he once owned.

The comments were reminiscent of previous times when Trump has attacked private citizens in deeply personal terms. Earlier this month, he was interrupted by the pastor of a traditionally African-American church in Flint, Michigan, after breaking his agreement not to be political in his remarks. Though Trump abided by her wishes, he went after her the next morning on TV saying she was “a nervous mess” and that he thought “something was up.”

In July, Trump assailed the parents of Humayun Khan, a Muslim U.S. soldier who was killed in Iraq in 2004, after the young man’s father spoke out against the Republican at the Democratic National Convention.

“I watched her very carefully and I was also holding back,” Trump said of Clinton, reflecting on the debate at an evening rally Tuesday in Melbourne, Florida. “I didn’t want to do anything to embarrass her.”

It’s unclear whether a Trump attack on Bill Clinton’s infidelities may help or hurt his appeal.

But Trump’s latest comments about Machado were striking in that they came just as he was working to broaden his appeal among minority voters and women — key demographic groups he’s struggling to win.

Clinton aides on Tuesday acknowledged they’d laid a trap for Trump.

“He seemed unable to handle that big stage,” said Clinton campaign chairman John Podesta. “By the end, with kind of snorting and the water gulping and leaning on the lectern that he just seemed really out of gas.”
