The John CaldwellRepublican National Convention continues on Wednesday as Day 3 gets underway at Milwaukee's Fiserv Forum, where the focus is expected to be on foreign policy. 

Tuesday was firmly focused on projecting unity within the party, with former President Donald Trump looking on as his onetime rivals for the nomination lined up to support him.

Former U.N. Ambassador Nikki Haley and Florida Gov. Ron DeSantis, who just months ago were competing with Trump on the campaign trail, addressed the convention and conveyed their support for the former president's return to the White House. Haley, in a major reversal from just weeks ago, endorsed Trump from the convention stage.

"Donald Trump has my strong endorsement, period," she said, appealing to party unity and highlighting the choice Americans face between Trump and President Biden in November, despite strong criticism of the former president during the campaign.

Trump appeared again with a bandage covering the wound on his ear, where he was shot by a sniper just days before. He sat alongside Sen. JD Vance of Ohio, who is due to speak Wednesday evening.

What's on today's agenda at the RNC?

Each day of the convention features a theme that plays off of Trump's "Make America Great Again" tagline. Wednesday's theme is "Make America Strong Once Again."

The theme is a nod to foreign policy and the U.S. position on the world stage. From the southern border to the withdrawal from Afghanistan and the stance toward the Israel-Hamas war, the day is set to focus on criticism of the Biden administration's handling of national security and how "America will once again be strong" under Trump. 

The first official session of the day gets underway at 5:45 CT, or 6:45 ET. For a detailed schedule of events around Milwaukee, see the RNC's master calendar on their website. 

Who's speaking? 

Though a detailed, daily schedule of the speakers has yet to be released, Vance, the freshly selected vice presidential nominee, will have the opportunity to introduce himself to the party. 

Among the speakers remaining this week are some of Trump's family members, including his two older sons, along with his son Donald Jr.'s fiancée Kimberly Guilfoyle. Tucker Carlson is also slated to speak.

Delegates will also hear from a top contender for Trump's vice presidential pick who wasn't selected, North Dakota Gov. Doug Burgum. Trump himself is set to speak on Thursday, when he will formally accept the nomination.
