What is the next step for the tea party groups who feel they were unfairly scrutinized by the Internal Revenue Service? For many of them, it may be lawsuits, against the IRS.

Jay Sekulow, the chief counsel for the American Center for Law and Justice, said the group will be bringing a lawsuit on behalf of many of those groups next week.

"It's the logical next step," he said.

"The admission and apology by the IRS that the criteria used [in tea party applications] was not correct and inappropriate" is grounds for a suit, Sekulow said in an interview with ABC News because groups he represents are "still getting letters requesting information," and he believes, "if we don't file suit we won't bring an end to this."
