Kyl must be formally sworn in to the position which is expected to happen by Wednesday. Once that happens, Kyl is able to participate in floor votes and other Senate business, though his committee assignments are, at least for now, unclear and up to the President of the Senate.
Can Kyl vote on Judge Brett Kavanaugh’s nomination to the Supreme Court?
Yes. Kyle has spent the past several weeks helping the D.C. Circuit Court judge navigate the confirmation process. Three attorneys familiar with conflict-of-interest laws and the confirmation process said Kyle’s work as a “sherpa” (carrier) does not amount to a conflict of interest.
