Bush, to help campaign.
"Don't fall asleep when I mention the name," Trump said, when he brought up Jeb Bush during a rally in Louisiana on Thursday.
"I see he's bringing his brother in now. He tried the mother, who's a very nice lady, I'm sure, but he tried the mother. That didn't work out so good," he said. "Now he's bringing in his brother."
Trump said he'd refrain from saying too much until after the former president makes a statement, adding "there's plenty to say about what happened."
"Especially that last three months, and especially getting us in that quicksand. You know, we got in quicksand," he said.
Trump has in the past called Jeb Bush an embarrassment to his family, which includes two former presidents.
During the rally, Trump also slammed President Obama for leaving the White House, vacationing in Hawaii and playing golf.
"If I get elected president, I'm going to be in the White House a lot. I'm not leaving," he said. "We have deals to make — who the hell wants to leave? You're there for a limited period of time."
"But more importantly, you have a lot of work do to," he continued.
He added that when Obama plays golf, he should "only play with people that are going to help our country."
"And that includes congressmen, so you need passages of legislation, which we don't get, so he signs executive orders all over the place."
"You should only play with people that can help you, including heads of foreign countries, like China, so that you can tell them that we're going to make a much better deal than we have right now. And if you told them on a golf course, it's a little bit easier, you know?"
