NYT:

The Internal Revenue Service said Thursday that it has delayed and is revamping new rules intended to curb political activity by tax-exempt groups and that were proposed after the agency was accused last year of targeting Tea Party groups.

The I.R.S. said it made the decision after receiving 150,000 comments — both positive and negative — about the proposal, the biggest public response to any proposed rule in its history. The decision postpones public hearings originally expected for this summer.
