Senator Ted Cruz defiantly refused to endorse Donald Trump in a speech he delivered at the convention center yesterday, stirring the crowd into a frenzy of booing. 

David Frum, senior editor at The Atlantic, chairman of Policy Exchange and former speechwriter for President George W. Bush, says that the Trump campaign saw the speech and approved it, only to have adviser Paul Manafort orchestrate the booing and tell reporters that he did it. He also talks about his latest article on why Melania Trump's speech will have a lasting impact.

Then, Congressman Leonard Lance, representing New Jersey's 7th District, and Congressman Lee Zeldin, Representative of New York District 1, give their take on Cruz's speech.

Zeldin was at the convention center during the speech and said that the outcry began when "the end was near and it was clear an endorsement wasn’t coming." He is hoping on the final day that "the best parts of people’s speeches is what punches through."
