With the Senate headed for a showdown over the minority party’s right to filibuster judicial nominees, on Monday evening centrist lawmakers concluded hours of negotiations that produced a deal preventing the “nuclear” option from going into effect.

Among the seven Republicans and seven Democrats who developed and signed on to the agreement are (from left) Sens. John McCain (R-Ariz.), John Warner (R-Va.), Ben Nelson (D-Neb.) and Mark Pryor (D-Ark.). Warner can be seen holding a copy of the “memorandum of understanding” that the group distributed to the media at Monday evening’s press conference.

According to that memo, the minority retains the right to filibuster a judicial nominee in “extraordinary circumstances.”
