RNC Day 2: Here's what to expect from the convention after Trump announced VP pick

Washington — Republicans from across the country are returning Tuesday to Milwaukee's Fiserv Forum for day two of the Republican National Convention, after a busy kickoff day that featured a formal nomination of former President Donald Trump, the highly-anticipated announcement of his running mate — and the former president's first public appearance since an attack on his life over the weekend. 

Delegates gathered on the floor of Fiserv Forum Monday afternoon, where the GOP adopted its 16-page platform, which was heavily influenced by the former president. The delegates went on to officially nominate Trump as the Republican presidential nominee before nominating his vice presidential pick, Sen. JD Vance of Ohio. Trump first announced Vance as his running mate in a social media post, calling Vance the "person best suited" for the job while touting his education, military and business records. 

A number of prominent Republican lawmakers, candidates and officials spoke on the first day of the convention, including Sens. Ron Johnson of Wisconsin, Katie Britt of Alabama, Tim Scott of South Carolina and Marsha Blackburn of Tennessee, Govs. Glenn Youngkin of Virginia and Kristi Noem of South Dakota, and Reps. Marjorie Taylor Greene of Georgia, Wesley Hunt of Texas, John James of Michigan and Byron Donalds of Florida. With a focus on the economy, the Republicans took aim at President Biden, while touting a better outlook under a second Trump administration.
