“Strong Island Hawk” is an Iowa Democrat and political researcher based in Des Moines. Prior to moving to Iowa, he lived in Washington, DC where he worked for one of the nation’s top public interest groups. In Iowa, has worked and volunteered on U.S. Representative Cindy Axne’s 2018 campaign and Senator Elizabeth Warren’s 2020 caucus team. 

Agents from the Internal Revenue Service Criminal Investigation division took the rare step in May of raiding Alliantgroup, a Houston-based firm specializing in energy tax credits Senator Chuck Grassley helped enact. Alliantgroup and its executives are frequent donors to Grassley; its National Managing Director, Dean Zerbe, is a former high-ranking Grassley staffer.

Months later, little is known about the raid, which followed IRS subpoenas and requests for documents. Some have speculated that the investigation is focused on Alliantgroup’s use of tax credits, including one provision Grassley and Zerbe had a big role in adding to the tax code.
