TOM LLAMAS: Already, Trump allies are preparing for a war at the convention. Long-time Trump confidant Roger Stone, a master of the dark arts of campaigns, now threatening delegates who may turn on Trump.

ROGER STONE: We will disclose the hotels and the room numbers of those delegates who are directly involved in the steal. We urge you to visit their hotel and find them.

DAVID MUIR (HOST): That comment making waves today. Tom live with us from Milwaukee, where Cruz supporters hope to celebrate tonight. And Tom, the bottom line here, if Donald Trump loses in Wisconsin tonight, that significantly increases the chances of a contested convention?

LLAMAS: That's right, David. A Trump loss tonight could register as his biggest setback yet in his push to clinch the nomination. Cruz no doubt would fight until every vote is counted, which could lead to a showdown at the convention.
