Trump takes aim at Biden, warns US being 'invaded' under Democrat president, likely 2024 rival

Former President Trump on Wednesday night took aim at his likely 204 presidential rival, Democrat President Joe Biden, during a campaign rally in South Florida in which he warned that America's national security is at risk. 

"Job No.1 is to make America Safe Again," he said at a rally in Hialeah. "I completely obliterated the ISIS caliphate ... I created the Trump travel ban to keep the radical jihadist terrorists out of the country. Under Crooked Joe Biden ... anybody can come in."

Trump spoke while just miles away in Miami the other 2024 GOP presidential candidates took the debate stage for the third time this election cycle, trying to distinguish themselves from the pack and cut into Trump's roughly 43-point lead on his primary challengers. 

Trump also said under Biden the U.S. is being invaded by dangerous, "bad people, terrorists like nobody has ever seen."

The former president's rally began with a short speech and endorsement from Arkansas GOP Gov. Sarah Huckabee Sanders, Trump's former White House press secretary.

"President Trump made us great and I know he will do it again," Huckabee-Sanders said.
