RNC Day 3: JD Vance accepts nomination for vice president as Trump watches on

Many of the speeches Wednesday will take aim at the Biden administration's handling of global issues, including the chaotic U.S. withdrawal from Afghanistan and the ongoing Israel-Hamas war, according to Trump's campaign and the Republican National Committee, with the theme of "Make America Strong Once Again."

"Under Joe Biden, the weakest commander-in-chief in our country's history, America has become a global laughingstock," the committee put out in an advance release.

Republicans see foreign policy as one of their strongest campaign issues, arguing that America's standing on the world stage was stronger under Trump despite the party's growing isolationist shift.

"I can tell you, countries around the world, leaders, are absolutely uncomfortable with the unpredictability of Donald Trump," Grenell, Trump's former ambassador to Germany, said during a reporters' roundtable Monday. "And when I say uncomfortable, that means they don't know exactly what he's going to do next. And that's a positive for us."

It is an argument he will likely make again Wednesday night.

While the focus of Wednesday's session is expected to be beyond America's borders, Republicans are expected to also highlight how Biden's supposed "weakness" on immigration is also endangering our reputation abroad. Many speakers have already documented claims that a growing number of foreign terrorists have been able to illegally get into the U.S. from Mexico. Republicans have pointed to the arrests last month on U.S. soil of eight people from Tajikistan with suspected ties to the Islamic State group.

Convention organizers are not expected to announce who will speak on the event's second day until later Wednesday morning.

Trump's survival of an attempted assassination Saturday at a rally in Pennsylvania was on the minds of many inside the convention hall. One of the delegates in the crowd could be seen with a folded white piece of paper over his ear - an apparent tribute to the bandage Trump wore when he entered the hall Monday to a roaring crowd.

He was wearing it again when he arrived Tuesday night, appearing even earlier than he did the night before. Trump entered a few minutes after his newly chosen running mate, Ohio Sen. JD Vance.

Many of the speakers so far have referenced the assassination attempt on Trump's life, and that's something we can expect to hear more of as speeches go on.
