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.
