Attorney General Merrick Garland said there should be "speedy trials" in the federal cases against former President Donald Trump.
Garland made his remarks during a CNN interview taped Thursday.
He noted that he agreed with special counsel Jack Smith that the "public interest requires a speedy trial in the election interference case."
"The matter is now in the hands of the trial judge to determine when a trial will take place," Garland said.
"The cases were brought last year," he said. "The prosecutor has urged speedy trials, with which I agree. And it's now in the hands of the judicial system, not in our hands. Special prosecutors followed the facts and the law. They brought cases when they thought they were ready."
He was asked about allegations that the Justice Department is going after Trump for political reasons.
"Of course it concerns me," he said. "What we have to do is show by the acts that we take that we're following the law, that we're following the facts."
Trump has repeatedly blasted the prosecutions brought by Smith and said those bringing charges against him will end up in a "mental institution" with "Trump Derangement Syndrome."
He has referred to Smith, as "deranged,'' and said the prosecutor was part of a team of "losers and misfits."
