With the Senate not meeting this week, a vote on an amendment todelay the implementation of the Federal Reserve's interchangerule won't happen until next week at the earliest.

Senate Majority Leader Harry Reid has said he will allow a voteon the amendment by Sen. Jon Tester (D-Mont.), to delay the implementation by 15months after lawmakers return from their Memorial Day break.Reid has said he will oppose the measure.

However, it's not clear what legislation the amendment will beattached to. In Senate parlance, they are looking for what inlegislative parlance is called an “amendable vehicle.”

Lobbyists for banks and credit unions who have been pushing forthe amendment have said the final vote will be close and declinedto predict if they have enough votes to pass it.

Normally the Senate stands in recess during Memorial Day breaksbut Republicans declined to agree to recess for fear that PresidentObama would use it to make a recess appointment of Elizabeth Warren as head of the Consumer Financial ProtectionBureau.

Instead, the Senate is meeting in brief pro forma sessions thisweek and conducting no business.
