Former President Donald Trump on Saturday further escalated his immigration rhetoric and baselessly accused President Joe Biden of waging a “conspiracy to overthrow the United States of America" as he campaigned ahead of Super Tuesday's primaries. Trump has a long history of trying to turn attack lines back on his rivals in an attempt to diminish their impact. Biden has cast Trump as a threat to democracy, pointing to the former president's efforts to overturn the results of the 2020 election.
