Donald Trump on Obama's national-security address: 'Is that all there is?'

Real-estate mogul Donald Trump fulfilled his promise to live-tweet President Barack Obama's major national-security Oval Office address on Sunday night. 

"BIG NIGHT ON TWITTER TONIGHT," Trump wrote earlier in the evening.

The Republican presidential front-runner further declared that Obama "MUST TALK RADICAL ISLAMIC TERRORISM!"
