A liberal activist who posed as a Christian conservative to record Supreme Court Justice Samuel Alito and Chief Justice John Roberts is the latest shot in a left-wing fight to undermine the high court.

Liberal activist Lauren Windsor attended the Supreme Court Historical Society’s annual dinner on June 3 and secretly recorded her conversations with both Alito and Roberts. Windsor’s recording comes as various activists and media outlets have hounded Alito in recent weeks over two separate instances involving flags flown at his homes: one instance in which an inverted flag flew at his primary residence and a separate instance in which an “Appeal to Heaven” flag was flown outside another one of his homes. Democrats have used the instances to demand Alito recuse himself from key decisions.
