Sen. Marco Rubio Tapped To Lead Senate Intelligence Committee

Marco Rubio has been appointed as the acting chairman of the Senate Intelligence Committee after Richard Burr stepped aside due to an FBI investigation into his stock transactions during the COVID-19 pandemic. The investigation focuses on potential insider trading violations. Rubio is expected to continue the committee's investigation into Russian election interference. Although typically he would have to give up his role as chairman of the Senate Small Business Committee, he may seek a waiver to lead both committees temporarily.
