Sen. John Thune used his first few minutes of floor time to make a commitment to defend the filibuster rule, which requires at least 60 votes to pass Senate legislation.

Republicans broadly support preserving the 60-vote threshold, which in most cases forces compromise to pass legislation through the Senate.
