U.S. Sen. Marco Rubio, R-Fla., weighed in on Thursday over the firestorm which U.S. Attorney General Eric Holder is facing as Congress continues to press him to release documents over the “Fast and Furious” operation.

Rubio took to Twitter and posted a simple message. “It's time for Eric Holder to resign,” he wrote.

Despite President Barack Obama invoking executive privilege to prevent Holder from releasing documents, the attorney general faces the possibility of having a contempt vote in the House against him.
