WASHINGTON (AP) — Lawyers for Donald Trump have asked the federal judge presiding over his election subversion case in Washington to recuse herself.

They say her past public statements about the former president call into question whether she can be fair.

The recusal motion Monday from Trump’s lawyers takes aim at U.S. District Judge Tanya Chutkan, a former assistant public defender who was nominated to the bench by President Barack Obama.

She has stood out as one of the toughest punishers of Jan. 6 defendants.
