The first day of the Republican National Convention has wrapped up in Milwaukee -- marked with an appearance by former President Donald Trump just two days he was wounded in an assassination attempt at a Pennsylvania rally on Saturday evening.

Despite the shooting, the gathering of more than 50,000 attendees, including an expected 2,400 Republican delegates, is slated to maintain its original programming as a time to bring the party together -- but now newly energized by Trump's amazing survival and raised-fist show of defiance.

One of the most anticipated moments of Trump's campaign happened Monday when Trump named 39-year-old Ohio Sen. J.D. Vance as his running mate.

Ron Johnson's opening salvo against Democrats

The convention's hometown senator, Ron Johnson -- a Trump ally, is the first speaker to rail against Democrats and President Biden, whom he said has made the country "less safe and far more expensive."

It marks the first sign of Republicans taking the offensive at the RNC.

He said Biden's 2008 promise to "fundamentally transform America" has come true -- and he said the U.S. is the worse for it.

Johnson said the Biden administration has brought "open borders, reckless spending and weakness on the world stage."

We must show the same strength and resilience as President Trump and lead this nation to a greater future world."
