'I have invited Biden to debate': Trump

STORY: "You tell me where," he said. "We're ready."

Trump made the comments after his criminal trial had concluded for the day.

Earlier on Friday, former National Enquirer publisher David Pecker testified that he suppressed a story about an alleged affair to help Trump's 2016 presidential bid, even though it would have boosted sales of his tabloid.

Pecker is the first witness in the case, which accuses Trump, 77, of falsifying business records to cover up a hush money payment to porn star Stormy Daniels.

Trump is the first former president to face criminal charges. The trial, which is expected to run through May, could be the only one of his four criminal prosecutions to be completed before his Nov. 5 election rematch with Democratic President Joe Biden.
