Krauthammer: Rubio Knocks Out Trump in 'Moment'

Fox News commentator Charles Krauthammer said a pivotal "moment" in the debate gave the "toughest fight" yet to Marco Rubio.

After Rubio questioned the billionaire about his specific healthcare plan, Trump would not  answer but critiqued Rubio for his earlier debate performance in repeating key lines.

Rubio struck back, saying Trump had "just repeated himself 5 seconds ago." The audience roared as Trump was ridiculed.

Krauthammer said Trump's failure to answer with details of his healthcare plan showed "there
was nothing there."

He lambasted the candidate for having seven months to prepare a "rudimentary" healthcare plan, adding that the debate showed Trump was all “bluster” and not much more than a powerful personality.
