Democratic senator criticizes Mayorkas' lack of responsiveness on border crisis

First-term Sen. Jon Ossoff, D-Ga., questioned Mayorkas during a Tuesday Senate Homeland Security Committee hearing on “Threats to the U.S.”

Ossoff asked the secretary about his department’s unresponsiveness to "a number of requests" sent by the Senate committee in July and why the committee still has yet to see "timely production of relevant documents and records."

"I also want to state here publicly for the record, while we’ve got you, that, regardless of the administration’s party, the Senate has an obligation to conduct vigorous oversight, to be assertive in using our authorities and prerogatives to secure the information necessary to oversee the executive branch’s past and current activities," Ossoff said during the hearing.
