Some 50 days after the D.C. Council voted to approve it, the Large Retailer Accountability Act passed to Mayor Vincent C. Gray on Friday for his signature or veto. A decision is likely to come this week, mayoral aides say, and there are still few indications that Gray will decide to sign the bill. But bill proponents are ramping up the pressure.

In a rare non-boilerplate transmittal letter, Council Chairman Phil Mendelson (D) invoked the Rev. Martin Luther King Jr. in urging Gray to sign. And a coalition of union, clergy and community supporters is promising to deliver petitions bearing tens of thousands of signatures to Gray this morning. Meanwhile, here is today’s e-mail reminder from Wal-Mart spokesman Steven Restivo: “There is a difference between standards for all businesses (a minimum wage) and arbitrary costs that discriminate against just a handful of businesses (the LRAA).”
