Republican presidential candidate former President Donald Trump and Speaker of the House Mike Johnson (R-LA) hold a press conference at Mr. Trump's Mar-a-Lago estate on April 12, 2024, in Palm Beach, Florida. 

Former President Donald Trump and House Speaker Mike Johnson pitched new legislation to crack down on noncitizen voting on Friday, despite the fact the practice is already illegal and occurs rarely.

Johnson said House Republicans would introduce a bill to require documentary proof of citizenship to register to vote, speaking at Mar-a-Lago next to Trump as he seeks to fend off threats from his right flank.
