Sessions is now expected to give his Senate testimony on June 13.

If Sessions attended this week's hearings, he would likely face lawmakers who could raise questions about the ongoing Russia probe and Trump’s decision to fire FBI Director James Comey at the attorney general's and deputy attorney general’s recommendation.

Comey's dismissal came amid an ongoing investigation into whether Trump campaign aides colluded with the Russians in the presidential election.
