Ahead of an expected vote this week in the Senate on expanding the Foreign Intelligence Surveillance Act, Sen. Barack Obama (D-IL) defended his decision to support recent compromise legislation. He wrote in a blog post on his campaign website that the bill “does not resolve all of the concerns that we have about President Bush’s abuse of executive power” but that a new provision in the bill “makes it clear to any president or telecommunications company that no law supersedes the authority of the FISA court.” A Senate vote on the measure is expected this week.
