The theme at the RNC on Wednesday is "Make America Strong Once Again."
Day three of the Republican National Convention centered around vice presidential candidate JD Vance as he introduced himself to Republicans as Trump's running mate.
The day was held under the theme of "Make America Strong Once Again."
Former President Donald Trump made an appearance at the convention hall to watch his running mate make his national debut. Other notable speakers included Trump's son and granddaughter and several Gold Star families who expressed their support for the former president.
Despite calls for unity, several speakers spent time bashing President Joe Biden, Vice President Kamala Harris and the Democrats on several issues including immigration, crime and Israel.
At times, the crowd joined into chants of "Joe must go" or "memaw" -- but they're not as enthusiastic as they've been other times this convention, despite the arena being a packed house tonight.
Many people remain seated as he speaks, even some the delegates on the floor.
As Vance went after Biden as a "career politician" and slammed his support for various trade deals over the years, the crowd joined in a "Joe must go" chant.
"I agree," Vance said.
Usha Chilukuri Vance, J.D. Vance's wife, is expected to introduce her husband as makes his first speech since being named Donald Trump's running mate.
The daughter of Indian immigrants, Chilukuri Vance is an experienced lawyer who has worked for major judicial figures, during her career.
She previously served as a law clerk to Chief Justice John Roberts, Supreme Court Justice Brett Kavanaugh, when he sat on the U.S. Court of Appeals for the District of Columbia Circuit and Judge Amul Thapar, when he was U.S. District Court for the Eastern District of Kentucky.
Chilukuri Vance worked at the firm Munger, Tolles & Olsen, until Monday when she resigned from her position, not long after Vance was named Trump's vice presidential pick.
The couple met while they were students at Yale University Law and married in 2014. They have three children.

Usha Chilukuri Vance was the penultimate speaker of the night and talked personally about their relationship and his work in the Senate.
Chilukuri Vance, a daughter of Indian immigrants, talked about how despite their differences she and her husband approached those differences with "curiosity and enthusiasm."
"Before I knew it, he had become an integral part of my family. A person I could not imagine living without. The JD I knew then is the same JD you see today. Except for that beard," she said to a laughing crowd.
"It is safe to say that neither JD nor I expected to find ourselves in this position. But it is hard to imagine a more powerful example of the American dream," Chilukuri Vance added as the crowd changed "JD."
"I am grateful to all of you for the trust you have placed in him and in our family," Chilukuri Vance said.
