During the rally, Trump baselessly told the crowd that if Abrams is elected, "your 2nd Amendment is gone."
Abrams has campaigned on increasing gun control in Georgia while "having respect for the 2nd Amendment."
Trump also said Abrams "wants illegal aliens to vote," a common criticism of Abrams referencing a video that surfaced of her saying undocumented immigrants are part of the so-call "blue wave" of Democratic voters expected to vote in this year's elections.
Abrams refuted that accusation in an interview with ABC News' Deborah Roberts. "I know that the only people who are allowed to vote are eligible citizens," said Abrams.
The president further riled up the crowd with references to the "caravan" of migrants moving from Central America towards the U.S.-Mexico border.
"You saw last week I called up the U.S. military, we’re not playing games," he said of the thousands of U.S. troops headed to the border just days before the midterm election. "Because you look at what’s marching up, that’s an invasion," he said. Trump also accused the caravan of including criminals.
Trump is scheduled to hold another rally on Sunday night in Chattanooga, Tennessee.
