Willie Robertson

The star of "Duck Dynasty" said America needs "a president who would have our back." Robertson, the first speaker Monday night, told the crowd that Trump is the candidate who will best support the military and police officers. Robertson joked that he and Trump had three things in common: they were successful businessmen, had hit TV shows and had wives "more attractive than we are."

Scott Baio

The television actor and former star of "Happy Days" said that "our country is in a very bad spot" and that "we need Donald Trump to fix this." He said that Trump isn't "a messiah." But Baio said Trump is someone he would "trust with the lives of our family and the health of our country." Baio also said, "To you first-time voters, I want to tell you what it means to be an American. It doesn't mean getting free stuff."

Sen. Joni Ernst

Iowa Sen. Joni Ernst, a rising star in the Republican Party, delivered a tribute to veterans. She and Rep. Ryan Zinke of Montana were joined on the stage by former members of the military. Ernst said "Hillary Clinton cannot be trusted. Her judgment and character are not suited to be sitting in the most powerful office in the world." She said the country can't afford a "lack of leadership."

Pat Smith

The mother of Sean Smith, who was killed in the 2012 Benghazi attack, asked: "If Hillary Clinton can't give us the truth, why should we give her the presidency?" She said she blames Clinton — who was secretary of state — "personally" for her son's death. Delegates also saw a video and presentation about Benghazi. "Hillary Clinton is a woman, a mother and a grandmother … how could she do this to me?"

David Clarke

The sheriff of Milwaukee County, Wis., began by declaring, "Let me make one thing absolutely clear: Blue lives matter." Clarke, who is black, has spoken out against the Black Lives Matter movement and blames its supporters for inflaming racial tensions. Delegates cheered his praise for the acquittal of officers in Freddie Gray's death in Baltimore. He said Trump was the "steadfast" leader the country needs.

Rudy Giuliani

The former mayor of New York called Trump a "man with a big heart. This is a man who loves all people … This is a good man." He said "What I did for New York, Donald Trump will do for America." He said Trump will declare war on terrorists, secure the borders and he excoriated the West's nuclear deal with Iran. He called Trump "an agent of change, saying: "In short, he will lead by leading and not following."
