The theme of Tuesday's session is "Make America Safe Again."
The second day of the Republican National Convention in Milwaukee ended Tuesday with appearances from some of former President Donald Trump's former rivals: former South Carolina Gov. Nikki Haley, Florida Gov. Ron DeSantis and entrepreneur Vivek Ramaswamy -- all calling for Republican Party unity.
They were joined by some of Trump's longest allies including Gov. Sarah Huckabee Sanders and Ben Carson in bashing the Democrats over what they claimed were harmful and failed policies.
The program focused on law and order with a theme of making the country "safe again."
Trump, with a bandage on his ear, made an appearance again Tuesday evening -- just days after he was wounded in an assassination attempt at one of his rallies in Pennsylvania over the weekend. Several speakers touched on that God spared Trump in the shooting, saving him for a divine plan for the presidency.
Arizona Senate candidate Kari Lake attacked Democrats' immigration policy during her speech.
"The solutions are really simple. Stop the 'Biden-vasion' and build the wall," she said before leading the crowd in a chant of "build the wall."
Perry Johnson, a Michigan businessman and one-time Republican presidential candidate who dropped out before any primaries, had a message for the White House.
"Michigan is the state that gave Trump the win in 2016, and Michigan will be the state that sends President Trump back to the White House in 2024," he said.
In 538's 2024 presidential election simulations, Biden wins Michigan's 15 electoral votes 60 times out of 100.
In addressing inflation and mortgage prices, Johnson said, "What do you say we fire Joe Biden?"
"Biden thinks things are looking up. The only person looking up is Joe Biden as he stares into space on the debate stage," he said.
Johnson addressed the assassination attempt against Trump, calling him the "toughest president since Teddy Roosevelt," before leading the crowd in chanting "Trump, Trump, Trump!"

Reince Priebus, the former RNC chair and Trump's chief of staff, took the stage, welcoming the crowd to Wisconsin.
He stressed Trump's accomplishments, stating: "While president, he decided to drill, baby, drill. He shut down the border, he confronted China head-on, made Europe pitch in on NATO, lowered taxes, put conservatives on the Supreme Court and he defeated ISIS."
Priebus, who also chaired the Wisconsin GOP, stressed how important the state is for Trump's victory.
"Let's stand united as Republicans. Let's stand united as Americans. Let's make America one again," he said.
