Reporter and with large crowds protesting outside, inside House Speaker paul ryan and two of trumps former rivals focussed on bringing unity of the Republican Party. Lets take our fight to our opponents with better ideas. Lets get on the offensive and stay there. Im proud to support donald trump. An extraordinary businessman, the right leader for a time such as this. It is time to come together and make sure that donald trump is the next president of the united states. Reporter and also here yesterday, indiana governor, mick pence, officially became the gops nominee for Vice President , and he will give one of the main speeches here later tonight. Back to you. Marcy, let me get this. I guess trump wasnt officially supposed to be the nominee until later on. What happened . Reporter right. Initially the gop said he wouldnt officially become the nominee on thursday when he had his speech. Instead, after the vote they declared mike pence and donald trump are the party nominees. It doesnt make that much of a difference. Its a technicality that changes when the fund raising begins and general election. A lot of talk throughout the course of yesterday about melanias speech. Any more of a response from the campaign . Reporter no. We still havent heard directly about those accusations from either donald for Melania Trump. They havent said anything. Trumps Campaign Manager has been outspoken, denying the accusations that she plagiarized the speech. He said the themes were just really personal to Melania Trump and clearly also personal to michelle obama. He says this whole thing has been blown out of proportion. And trump is now banned from using songs from the rolling stones, adele, kneel young, twisted sister, rem, and as of the first night, queen. Whats he going to do thursday night . Reporter yeah. I dont know. Hes going to have to just hum to himself. I dont know. As for the queen song, its not official that hes not going to be able to use that song. There was some controversy, though, because they played we are the champions, and then queen, the group thats representing queen, put out a message saying theyre frustrated by the repeated unauthorized use of the song after previous requests to desist which has obviously been ignored by trump and his company. It says queen does not want to be associated in any way with mainstream or political debates, but the rnc communication director tweeted that the Gop Convention actually paid to license the song specifically for use here in this arena, so the plot thickens. Reporter you might still hear the song. And not the first time the president ial candidate has dealt with it. I feel like we deal with this almost every year. Well with b be checking in with marcy throughout the morning. A governor of ohio, john kasich, staying away from the rnc, but yesterday he came pretty close. Kasich held a reception at the rock and roll hall of fame a mile away from the convention. He thanked nearly 2,000 Ohio Republicans for their support, and he said he left the race because he felt if he had gone forward, he would have had to tell people things he doesnt believe are true. Concerning words from another Top Republican who shied away from donald trump, george w. Bush reportedly told former aids hes worried he could be the last republican president. According to politico he made the comment this past april. Thats when the primary was down to trump and cruz. And some Convention Speakers are on thing not to mention trump by name, suggesting they may be lukewarm about his candidacy. But virtually everyone is on the same page when it comes to blasting Hillary Clinton. Lets get more now from rick kline. Good morning. Reporter a trump Family Affair, night to of the Republican National convention in cleveland. Tiffany trump and donald trump junior giving well received speeches about their dad. This campaign is in search of unity in terms of people being angry. Some delegates had their arms crossed. And energy, there is not an emotional core yet not a lot of glitz and glamour we expect around donald trump. Thats his challenge. The only time this convention got into it is when they found new ways to insult Hillary Clinton or find new phrases to describe the anger they feel.
