[ cheers and applause ] >> this has been an unusual campaign and the start to this year's republican national convention, it was kind of unusual, too. >> it was. donald trump's wife melania introduced herself to the world tonight. that was after speakers who took on the black lives matter movement hillary clinton's handling of the attacks in bengha benghazi. >> and an introduction by her husband that we've certainly never seen before, the candidate appearing on stage before the last night of the convention arriving like a rock star. news4 has team coverage tonight from quicken loans arena in cleveland starting with steve handelsman and what we saw on day one. >> reporter: donald trump ignored yetot tradition and came to his convention on the first night. >> we're going to win. we're going to win so big. >> reporter: he was the warm-up act for his wife melania. >> an amazing mother, an incredible woman, melania trump. >> reporter: melania, 46, from slovenia was a model now a mom, married to donald in 2005. >> if you want someone to work for you and your country, i can assure you, he's the guy. >> reporter: the convention began with conflict. anti-trump forces disrupted, demanding delegates decide if trump delegates can vote for somebody else. you don't want trump to be the nominee. >> i personally don't want trump to be the nominee. the world just got to witness the tyrannical man who will stomp the grassroots. >> reporter: like melania trump said, she has. the trump campaign already out with a video showing today's anti-trump disruption. i'm steve handelsman, nbc news at the rnc in cleveland. >> and our team coverage continues now with news4's chris lawrence. he's inside the arena now. >> he went to see how the message was getting to people outside. what were you hearing tonight? >> reporter: bottom line, that a lot of women, a lot of republican women are just fine with donald trump as their nominee. look, they don't like the fact that he made that snide comment about carly fiorina's face or called rosie o'donnell fat. but they're not looking at those comments in a vacuum, and they refuse to just write him off. >> the way he reacts and says things, yeah, that bothers me. but the big picture for me and where america is going. and i can't go the other way. i can't go with hillary, i just can't. >> he's a beautiful man. he's a family successful and good people, and i think that shows a lot about somebody. >> reporter: so look, there is a reason that melania trump was the headliner of the first night of the convention. there was a reason she talked about her husband. there was a reason that you heard rudy giuliani use words like friend, husband, father, grandfather. these are not the words that pop into your mind when you think of donald trump, but this is part of the appeal, part of trying to rework his image to appeal to those all-important female voters. jim, doreen. >> reporte >> chris, you were right in the middle of that chaos that erupted on the floor this afternoon. give us your impression of day one right out of the gate they came out. >> reporter: yeah, two things, jim. there is a fracture in the party, no doubt. we saw that play out when you're watching ken cuccinelli badge around, people shouting and booing rhein preibus, the president of the rnc. you can see this isn't a tightly controlled convention. i say that because on one hand, you've got people delivering this message down here about pull up your bootstraps, work hard, you'll get ahead, this is america. well, that sort of runs counter to what donald trump's fabulous appeal has been, that these trade deals have rigged the system, that it's not enough to work hard, that there are forces in machine to keep the american man from succeeding. there is sort of a cross-current, and that's one of the things that sort of jumped out at me tonight. again, we've got a few days to go, and this could be a very unified convention by the time we're standing here on thursday. >> stay tuned. as we've seen, anything can happen. chris, thank you so much and stay with us for our continued coverage of the rnc all week long. chris and

match his asking price, saying they could hire somebody else if needed. he thinks the team is risking it, not cousins. >> he has to come out of this with 20 million. for the team, the risk is cousins is going to be great and you're going to have to pay him a gigantic contract next year based under the franchise tag, or you let him go to market and let the market set his value, and he decides he's going to go with someone else and you don't have a replacement who ends up being capable and cousins goes on to be a star with other teams. there is more risk for the team, i think, than for the player at this point because the team never put enough money on the table that created the kind of risk that would make the player >> mike florio of football talk. i wish i could say that wraps up the
