Timeline of Towergate

The Conservative Treehouse blog has a timeline of Obama administration wiretapping of Trump campaign personnel and equipment. Here is their summary.

The Obama administration sought, and eventually obtained, authorization to eavesdrop on the Trump campaign; continued monitoring the Trump team even when no evidence of wrongdoing was found; then relaxed the NSA rules to allow evidence to be shared widely within the government, virtually ensuring that the information, including the conversations of private citizens, would be leaked to the media.

If they happened as alleged, those actions are just plain wrong.
