A Fulton County judge heard arguments Tuesday about District Attorney Fani Willis’s refusal to comply with subpoenas issued by the Georgia legislature, marking the latest instance of Willis fighting outside scrutiny of her prosecution of President-elect Donald Trump.

The hearing centered on a pair of subpoenas that a state Senate committee sent to Willis in August seeking her testimony and documents. Willis asked a judge to void them, arguing that the special committee, which was established this year to investigate Willis, did not have subpoena power.
