The Senate Judiciary Committee has announced plans to issue subpoenas to three individuals in connection with a probe into ethics practices at the Supreme Court. The 11 Democratic members of the panel are targeting two wealthy Republican donors and an influential conservative legal activist in order to uncover more information about the trips provided to two Supreme Court justices. The investigation is a significant escalation of the Democrats' efforts to hold the high court accountable, and the subpoenas could provide important insight into the relationship between the justices and wealthy donors.
