Elizabeth Warren demanded Monday that Senator Scott Brown release more years of his tax returns. The only problem was that Brown, her Republican rival, had already released six years of tax returns while Warren has refused to release more than four years of her filings.

Asked to reconcile that apparent conflict, Warren backed off her demand hours later, saying Tuesday that six years was enough. She did not, however, offer to release any more of her IRS filings.

Both candidates were asked by the Globe in April to release six years of tax returns. Brown agreed to allow reporters into his campaign office to inspect all six years of documents. Warren would only agree to allow reporters to inspect four years worth of returns, releasing some documents outright and allowing reporters into her office to review the supporting documents covering the same period.
