Donald Trump said that he regrets leaving the White House after losing to Joe Biden in 2020, and repeated his claim of “stolen elections.”

Trump was speaking at a campaign rally in Lititz, Pennsylvania on Sunday, where he said the US had turned into “a failed country” under the leadership of an “incompetent group of fools.”

RT reports: He went on to accuse the Democratic candidate, Vice President Kamala Harris, of being unable to prevent the flow of illegal migrants across the border from Mexico.

“We had the safest border in the history of our country, the day I left,” Trump said. “I shouldn’t have left. I mean, honestly, because we did so, we did so well.”

Trump labeled the Democratic Party a “corrupt machine” and claimed that the integrity of the election could only be guaranteed if US states use exclusively paper ballots and require voter IDs. “In California, you are not even allowed to ask for a voter ID. They are only doing it because they want to cheat,” he said.

Trump has never admitted that he lost the 2020 election, despite courts failing to find evidence of widespread voter fraud. He eventually stepped down as president after a crowd of his supporters stormed the US Capitol building on January 6, 2021, briefly interrupting the certification of Biden’s victory.
