The Senate Judiciary Committee voted on Thursday to issue subpoenas to conservative activists Harlan Crow and Leonard Leo, as part of an investigation into ethics practices at the Supreme Court. Republican members of the committee walked out of the room during the vote, accusing Democrats of attempting to undermine the court. The investigation was launched after reports revealed the court had failed to properly disclose gifts and travel expenses from conservative groups. The committee is now requesting information from Crow and Leo, as part of a new ethics code that requires justices to disclose gifts and travel expenses and recuse themselves from cases in which they have a financial interest.
