Marco Rubio tried to fend off GOP presidential rivals’ attacks on his past support for comprehensive immigration reform Sunday by insisting he would not advocate his own comprehensive immigration reform bill if elected.

“That’s not how we’re going to do it when I’m president,” Rubio said when asked by “Meet the Press” host Chuck Todd why he won’t simply repudiate his 2013 support for the “Gang of Eight” immigration bill. “That’s not going to be the law that we’re going to pass.”
