Eric Trump Using 'Zero' Speechwriters for RNC Speech

Eric Trump's speech tonight at the Republican National Convention will come from his heart and be in his own words, he promised today.

"Zero," Trump said on "Good Morning America" when asked whether any speechwriters helped compose his address in support of his dad, Donald Trump. "I wrote every single word of my speech myself."

"I think sometimes when you write from the heart, and I'll certainly deliver it from the heart, the product will be what it will be," Trump, 32, added. "But it will be certainly sincere and full of love and full of emotion and that's how it's supposed to be."
