Donald Trump was defeated by Joe Biden in 2020 and was impeached by the House of Representatives. He was found not guilty in his second impeachment in 2021 and is currently allowed to run again in the 2024 presidential election. If he decides to run, he would be seeking to become the second president, after Grover Cleveland, to serve two non-consecutive terms, potentially making him both the 45th and 47th president of the United States. The last president to run after leaving office was Theodore Roosevelt, who came in second in the 1912 election as the candidate of the Progressive Party, although Herbert Hoover did seek the Republican nomination at national conventions after leaving office in 1933.
