Trump tweeted that it was “funny” that Jeb Bush didn’t “want help from his family in his failed campaign and didn’t even want to use his last name.”

Trump asked in a later Tweet if George W. Bush's appearance means he is "fair game" for questions about the World Trade Center, Iraq War and "eco collapse."

Jeb Bush and George W. Bush are scheduled to appear together at their first campaign rally Monday evening in North Charleston, S.C., ahead of the Palmetto State’s primary.

George W. Bush, who is popular in South Carolina, last week was featured in a radio ad in which he touted his brother as a "steady leader."

"We live in troubled times, with the military deployed around the world. We need a strong leader with experience, ideas and resolve," the former president says in the ad.

Trump earlier this month said Jeb Bush "had to bring in mommy” for help after Barbara Bush said it was “unbelievable” to think that women could support the real estate mogul.

“Wow, Jeb Bush, whose campaign is a total disaster, had to bring in mommy to take a slap at me,” Trump tweeted then. “Not nice!”
