The chair of the Texas House Democratic caucus remained defiant Thursday in the face of one US senator’s bid to enlist the FBI’s help in returning him and his state House colleagues to the state.

S en. John Cornyn, a Texas Republican, said on Thursday that FBI Director Kash Patel has granted his request for the federal government to assist with locating Texas House Democrats who fled the state in protest of GOP-led redistricting efforts.

Texas Republicans have been trying to bring the state Democratic lawmakers back in order to vote on their redistricting plan.
