Bush family values: 43 comes to Jeb's rescue

(CNN) - Jeb Bush, who has struggled with the political baggage attached to his famous last name, has finally come to a place where his family is not a liability: South Carolina.

This state has been good to the Bushes, handing key primary victories to both George H.W. Bush and George W. Bush in their White House bids. As Jeb Bush looks to continue his family's winning streak on Saturday in the first southern primary, his campaign is becoming an all-hands-on-deck family affair.

George W. Bush will stump for his younger brother for the first time Monday night, attending a rally in North Charleston along with his wife, former first lady Laura Bush.

The rally comes after Jeb Bush's most forceful debate performance of the campaign, when he pushed back on Donald Trump for attacking his brother's national security record.

"I'm sick and tired of him going after my family," Jeb Bush said Saturday night. "My dad is the greatest man alive, in my mind. While Donald Trump was building a reality TV show, my brother was building a security apparatus to keep us safe and I'm proud of what he did."

It was clear that the audience was on Bush's side, as it loudly booed Trump and cheered for Bush.

But Trump wasn't letting go of his line of attack Monday morning, vowing to come after both brothers if necessary. Read more.
