Washington (CNN) President Donald Trump attacked the jury forewoman in Roger Stone's criminal case again on Sunday, repeating claims that she was biased and therefore unfit to participate in his longtime friend's trial last November.

"You have a juror that is obviously tainted. She was an activist against Trump. She said bad things about Trump and bad things about Stone," the President claimed without evidence. "She somehow weaseled her way onto the jury and if that's not a tainted jury then there is no such thing as a tainted jury."

The President's comments this week follow Stone's attempts to raise doubts about his conviction. In recent days, he has sought a new trial and asked the judge to remove herself from his case.

Both of these types of requests often don't succeed in court, but they have allowed Trump to continue to question Stone's trial publicly, where a jury in Washington unanimously found Stone guilty on seven counts that revolved around him protecting the President.
