Thomas and Alito's acts of corruption and expression of their biases have been well-documented, and regardless of other happenings along the US political landscape, the public must pay attention to their lack of ethics. Even if these articles go nowhere, their filing — and actions taken by other lawmakers — prove Democrats are serious about holding justices on the nation's highest court accountable.
AOC is drumming up bogus accusations in the hopes of kicking constitutional conservatives off the court and replacing them with left-wing activist judges. Thomas is being targeted because he went on vacation with a wealthy friend and his wife happens to work in politics, and Alito because his wife flew a conservative flag outside their house. Neither of these things is unethical, but that doesn't matter to the left in their pursuit of changing the court forever.
