DONALD Trump tonight blasted criminal charges against him for allegedly keeping secret documents as “a travesty of justice”.
Chanting supporters greeted the former US president when he appeared in public for the first time since being indicted.
He told them his treatment was reminiscent of “Stalinist Russia and communist China”.
In his Republican convention speech, Trump insisted: “This vicious persecution is a travesty of justice.
“Biden is trying to jail his leading political opponent.”
Trump also said of his White House rival: “There has never been a president so corrupt.”
He is due in court in Miami on Tuesday to face 37 charges of retaining files on nuclear weapons, foreign militaries and CIA operations.
Prosecutors say he stacked boxes of documents at his home in Mar-a-Lago, Florida — including in a shower.
Trump, who is 77 on Wednesday, is tipped to be the Republican nominee for the 2024 presidency, but experts say his bid could now be derailed.
Ally Mark Levin, chief of staff to 1980s president Ronald Reagan, said: “Joe Biden is the crookedest crook ever in the Oval Office.”
